Good Luck To You on Friday the 13th

Whether you're superstitious or not, I wish you the best of luck this Friday the 13th.

Superstitious by Shel Silverstein

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

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

And if you ever spill some salt you'll thrown some 'cross your back,

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

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

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

Or open an umbrella when you are in the house.

You'll bite your tongue each time you say

A thing you shouldn't have said.

You'll hold your breath and cross your fingers 

Walkin' by a graveyard,

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

Black cats will all look vicious, if you're superstitious,

But I'm not superstitious (knock on wood).
