The Facts of Life

Yesteday I stumbled upon the following conversation between our young sons:

Little Brother: Hey! Did you know Elmo hatched out of an egg?

Big Brother: Did not.

Little Brother: Did too!

Big Brother: Did not! Furry animals can't hatch out of eggs. They get born from their mommy's tummy.

(Long pause)

Little Brother: But Elmo's not an animal. He's a furry monster!
