Belly Buttons

My son has always had a fascination with belly buttons.  I don't know why.  He just seems to think they're cute.

"Mommy, does the dog have a belly button?"

"Yes.  Somewhere under all that fur is a belly button."

"Can I look?"

"Have at it, kid.  But don't blame me if he nips your fingers."

He searched and searched, but could not find the belly button on our German Shepherd.  Maybe he's a mutant.  That would explain a lot of things.

"Mommy, what are belly buttons for?"

"What do you think they're for?"

He thought about that.  "Well, I know what mine is for."

"What?"

"It's for pressing.  And when I press it, I go 'beep.'"
