My son is five (and a half he would say). After his bath today he didnt get dressed for some reason.
I didnt think it was any big deal, there's no one here but us.
He's been playing around the house, I cant see him but I can hear him playing.
I hear him bouncing on the hippity hop ball. It looks like this for those who dont know.

You sit on it and hold the handle between your legs and bounce. Quite a good time.

Anyways...
I hear him say "OOOOooow."
He walks in holding his crotch and whines, "MOOOOOOOooommmmmiiieeeee?"
I say "Son, I dont want to know. Just dont hippity hop NAKED, OK?"
He says "OK, mom" and walks away.

I'm glad I can teach him the REAL important life lessons.
