Superstitious by Shel Silverstein

If you are superstitious you'll never step on ____________.

When you see a ____________ you will never walk beneath it.

And if you ever spill some __________ you'll throw some 'cross your back,

And carry 'round a rabbit's _______ just in case you need it.

You'll pick up any __________ that you find lying on the ground,

And never, never, ever throw your ________ upon the bed,

Or open an __________ when you are in the house.

You'll bite your _________ each time you say

A thing you shouldn't have said.

You'll hold your breath and cross your _________

Walkin' by the graveyard,

And number __________'s never gonna do you any good.
