Break a mirror: bad luck.
No take backs. You’re stuck.
Black cat crosses you?
Nothing to do:
bad luck.
Walk under a ladder, same again.
Step on a crack?
Guess what then?
Bad luck, bad luck, bad luck.
So get a rabbit’s foot
and a four-leaf clover,
and throw salt over your shoulder
twice a day.
But of course, bad luck might get you, anyway.
