Horror of Horrors!

You hold yourself very, very still.
Don't move, you order yourself. Think like a statue.
Your nose starts to itch.
Don't think about it. Ignore it, and it will go away.
But it doesn't! The itch gets worse. You have to scratch!
You lift your hand from the chopping block. Just as MagnifiCAT brings down the cleaver.
Oops. You must have tipped forward when you reached for your nose. MagnifiCAT didn't cut off your hand. He cut off your head! Too bad you couldn't think more like a statue. They never have to scratch. And they usually keep their heads!
