Worm Eating

Little Johnny sat playing in the garden.

When his mother came out to collect him, she saw that he was slowly eating a worm.

She turned pale. No, Johnny! Stop! Thats horrible! You cant eat worms!

Trying to convince him further, Now the mother worm is looking all over for her nice baby-worm.

No, she isnt, said Johnny.

Why not?

Because I ate her first!
