Now as a man I like a compliment as much as the next fella but when I'm having my morning pee it's a little disconcerting to have 3 year old DD say "my like your willy" in mid flow, shortly followed by "my wish my had a willy" cue concerned father trying to explain that you don't need a willy to do anything you want. This argument was instantly shot down when DD asked if she could "do my wee standing up like you daddy?" Ahh bugger!
Game set & match to 3 year old.
