Anybody here familiar with the show Whose Line Is It Anyway? The link below is to the funniest clip I've ever seen on Whose Line. It's a little long but keeps getting funnier the longer you watch.

They don't often get that funny, but it's usually pretty good.  My 11 year old son generally has it on TV (I don't keep track of TV schedules, but he does.).

I've never seen this clip on TV just on the internet, but I laugh my tail off every time I see it.

My favourite bit is the ABC Family caption - suitable for all ages? Well, small children probably have a hard time figuring out why everybody's laughing that much
