GARY LARSON.

Daddy,
he said.
There are a lot of worms around here, but you have to be careful when you pick them out of the dirt so you don't accidentally pull off their tails.

- Okay pal,
I said.
Thanks for the heads-up. And just how do you know this?

He looked up; the world weariness of those who have seen much and remember what they want to forget, and then looked away; we stood silently as the breeze wheezed past and a herd of orphan worms tunneled inches beneath our feet. 

I'm sorry.
He whispered. 
It was a accident.
