I can count the number of famous people I’ve met on one hand, and by famous I mean my mum has heard of them. Two of these encounters were work-related: I had to show the film producer David Puttnam and the journalist Kate Adie around the university once, while the third occurred when the Green Cross Code man came to my school in 1983 to promote road safety and The Return of the Jedi (and not necessarily in that order). I asked David Prowse if he really was Luke Skywalker’s dad, and the barefaced liar told me that he wasn’t.*

However, if there’s famous, there’s also Doctor Who-famous. Now, my mother might not recognise them but if I had to talk to, say, Paul Cornell or Graeme Harper, then I’d experience exactly the same sense of tongue-tied awkwardness I’d feel if I had to talk to George Clooney or Steven Spielberg – well, maybe not as bad as that. The point is, I would probably be able to chat to them normally as long as nobody mentioned Doctor Who.

If you are a Doctor Who fan, it is comparatively easy to meet your idols and put the fear of God into them. I once accidentally spent half an hour in the company of Wendy Padbury, who played the Second Doctor’s companion, Zoe, over forty years ago and still has to suffer the attentions of over-excited middle-aged men. Wendy was smoking at the time, as was I. I recognised her immediately. However, I didn’t want Wendy to think that I was just another sad Whovian with only one thing on his mind so I made polite small talk about the weather and the rising costs of pet insurance instead. Wendy was delightful, and she gave me some very sage advice about fixed-rate mortgages, but by the time she finally got up to leave, I was exhausted. But I had done it. I had got through it without once mentioning the D-word.

This partly explains why I didn’t go to a Doctor Who convention until I was well into my thirties. Also, I couldn’t see the point of them. Why would I pay to listen to actors and directors telling the same stories that I’d already read in magazines and books a hundred times before? But in 2003, the year Doctor Who celebrated its fortieth anniversary, a convention called Panopticon announced that every surviving Doctor would be in attendance at the Metropole Hotel, London, in November to mark the special occasion. It sounded like an opportunity too good to miss.

The first thing that struck me when I walked into the lobby of the Metropole wasn’t the home-made Dalek bumping into the furniture, or even Mr Bronson from Grange Hill posing for a photograph with the concierge. No, it was the line of beautiful women standing at the check-in desk. I’d never seen so many gorgeous women assembled in one place before. Seriously, these women were stunning.

These women were supermodels.

No, a supermodel convention was taking place in the same hotel, in parallel with ours. So one half of the hotel was full of beautiful women while the other half, well, wasn’t. There wasn’t a great deal of crossover between these two events, although this didn’t stop several guests from my side of the divide from trying. If one of the supermodel panels that weekend had been a master class in how to avoid being chatted up by men who liked to punch well above their weight, then they certainly had ample opportunity to put what they learned into practice every time they went to the bar.

I can’t speak for the supermodels but the convention I attended was a disaster. Three out of five surviving Doctors failed to materialise, while the absence of an event timetable meant it was practically impossible for anyone there to locate any of the panels they wished to attend and/or avoid. Couple this to the fact that it cost more money to buy a pint of lager than it did to buy a Tom Baker action figure from the dealer’s room, and that the cashpoint in the lobby had been hacked so when you got home you discovered that your bank account had been emptied, and my overall impression of conventioneering was that it was an expensive, and frankly disappointing, hobby, one I had been entirely justified in avoiding for the previous thirty-odd years.

But at least I got through that weekend without having to speak to anyone who might make me feel nauseous and inadequate, other than the supermodels. The closest I got was when I accidentally held a door open for Paul McGann. I couldn’t believe it. He was tiny.

Although I have never spoken to a Doctor, a Doctor has spoken to me. Well, I say, spoken. Attacked is more accurate.

I blame Issue 1 (of 1) of the Tachyon TV Fanzine. It was 2006 and the website of the same name was still soldiering on, mainly thanks to my friends John Williams and Damon Querry. We had decided that it might be fun if we transformed our digital fansite into an old-fashioned printed fanzine. It would be a one-off homage to a simpler time, when expressing your love for a television programme had more to do with Letraset and glue than HTML coding and CSS style sheets. The finished fanzine was a light-hearted and affectionate celebration of Doctor Who and its funny little ways. It included reviews, its very own Agony Aunt, a pin-up poster of Adric and even a couple of songs. We were so proud of it, we decided we would hand out free copies at a local Doctor Who convention in Stockton-on-Tees. John and Damon drove to the hotel on the Friday night with hundreds of copies bundled in the boot of their car. I planned to join them in the morning and help distribute them.

John texted me just as I was climbing into bed:

Just gave Colin Baker a copy of the fanzine.

This was unexpected. Colin Baker wasn’t supposed to be at the convention. I texted back:

You gave Colin the fanzine? Are you INSANE?

John may have been too drunk to remember what was in our fanzine, but I wasn’t. I knew its contents inside out, specifically the cheap joke on page 17 about Colin Baker’s weight. It was a barely legible 6-point headline on the cover of an imaginary back issue, but it was there all right:

COLIN BAKER: THE TRUTH, THE WHOLE TRUTH AND A TRAY OF DOUGHNUTS

I don’t know who came up with this joke. It’s not remotely amusing, is it? All I know for sure is that it wasn’t me. I also remember thinking at the time that no possible harm could come of it because Colin wouldn’t be at the convention, and I doubted that he collected Doctor Who fanzines in his spare time, so the chances of him seeing the offending remark were slim.

The next morning, after a sleepless night, I arrived at the convention hotel to find John and Damon sitting in the ballroom, waiting for the first panel of the day. They looked a little the worse for wear, but that didn’t stop me from chastising them for their spectacular lapse of judgement the night before.

The first panel of the day wasn’t supposed to be anything special – a couple of guest actors with small parts in the new series according to the convention timetable – so when I saw Colin Baker striding purposefully towards the stage with something rolled up under his arm, I knew that something had gone terribly wrong. And I wasn’t just talking about the timetable. Colin didn’t look very happy when he took his seat, and the interviewer’s first question didn’t improve his mood.

When Colin spat out the word ‘parasite’, I could sense John’s back straightening in the chair next to mine.

I glanced at John. John didn’t glance back.

Colin held up a copy of our fanzine for the crowd to inspect. It looked like it had been scrunched up and thrown across the room a few times.

The crowd applauded. John joined in.

A woman sitting two rows in front of us stood up and cheered. I sank into my chair as the applause swelled. Two more fans stood up. Flaming torches were lit and smoke alarms starting going off.

I sat through the rest of Colin’s panel in stunned silence and when it was finally over, I sheepishly turned to my friends to confirm that I hadn’t imagined it and a bona fide Doctor had just slagged us all off. John shrugged his shoulders. Damon had obviously been crying.

This put me off conventions for a while, especially conventions that Colin might turn up to (and he turned up to a lot). We tried to make ourselves feel better by selling the last remaining copies of the fanzine online and we donated the proceeds to a charity that Colin was the patron of, but I don’t think Damon ever fully recovered from the haranguing he received that morning; he adored Colin. I still occasionally wake in the middle of the night with the ex-Doctor’s words ringing in my ears and John refuses to discuss the incident. I suspect – I hope – that Colin hasn’t given it a second thought.

However, back in the present, with the experiment well under way, I began to think that it might be fun to expose Sue to the special thrills of the convention circuit. So meet me back here after the next chapter and I’ll tell you about something even worse.

* I also went to the same school as Clive Owen, but he was three years older than me so we only ever shared assemblies and fire drills, and he wasn’t exactly famous back then either, except amongst the girls in the lower sixth.
