Wa wa waaaaa

My 2-year-old son is being potty trained. 

Today his mom noticed he'd let loose in his pull ups and asked him what happened. He got a real sad face and said "Wa, waaa, waaaaa."

You know, that trombone sound that you hear when a joke doesn't fly? Yes, that "waa, waa, waaaaa." Where does he get this stuff?

I personally think you shouldn't be that cool until after you've learned not to pee yourself.
