There was a little boy with a speech impediment. He asked his father, "Dabby how tum I tawk dis way?" The man said he was busy, so go ask mom.

He finds his mom and asks, "Mobby, how tum I tawk dis way?" She tells him she's busy too, go ask somebody else.

The little boy walks outside and sees the postman. "Mibster, how tum I tawk dis way?"

The postman leans down and whispers "Hush your mouf... You wanna dit us bof killed?"
