Yes, that's a big claim for a title; but this really is the funniest cat video ever.  Cute and cuddly one second then crazed ball of fur and claws.  You don't want to laugh, but you have to...you can't help it.  Oh, and for the record, the cat on the fan is a fake...it was computer generated...so don't get your fur fluffed about it!  Just Enjoy!
