"The X-Factor" may not be airing in the US anymore, but it's still going strong in London. Of course you still have the crazy auditions that are always entertaining, but the 17 and 18 year old singing duo that auditioned for this season take the cake. Not only was their audition terrible, their attitude horrid, but what one did to the other at the end was priceless! You can see the epic punch at the 2:15 mark.
