Remember when you were a kid and your mum threatened to wash your mouth out with a bar of soap when you swore? Well, fill the bathtub for this boy.
When this (rather mischievous) uncle asked his nephew to tell him all the 'naughty' words he knew, the boy – who's around four years old – took off with relish.
'Crap,' was the first utterance from his innocence lips, followed by a magnificent flourish of 'butts' – butthead, butt-crack, butt-mouth, even butt-TEETH!
So far, cutesy cute – but wait until the last word on this clip, which has already been viewed over 300,000 times.
Your jaw will drop!
