Superstitious

You say you're superstitious yet you still believe in me.
So does that make me a black cat or the number 13?

You won't walk under ladders, but you'll walk all over me.
Be careful not to break a mirror; my heart can shatter for free.

So while you cross your fingers and count all of those crows,
I'll take your rabbit's foot and chop off all its toes!
