That reminds me, when my daughter was young, she was going on about Def Leppard, whose records she'd been playing at full boost in her room, fo the discomfiture of the entire household.
I said: "Yeah, he must be deaf, to make that noise!"
She: "Daa-aad, that's spelled D-E-F!"
Me: "Oh, he can't spell, either?"
