Kimmel tests kids on bad words

"Stupid", "hush" and "shut up" were as foul as it got for one young pony-tailed girl.

"I know 'ass', I know 'bitch'," said a boy, slightly older, before adding "screwed" and "sucked" to his list.

US talk show host Jimmy Kimmel decided to test children's vocabulary on "naughty words" with a little street vox pops in Los Angeles.

Inspired by a recent viral video of a toddler asked to rattle off all the bad words he knew, Kimmel sent a camera crew to Hollywood Boulevard to ask a few innocent young ones to repeat every bad word he or she knew.

The hilarious results aired on Jimmy Kimmel Live last night.
