I came across this site a weeks ago and have been going back. The Will Ferrell landlord video has been viewed more than 50M times and is very funny (Not office friendly).

Poor Tom Cruise. Jerry O’Connell does a great Cruise a great parody. As an aside, the new sitcom he is in  the Carpoolers is actually very funny. After all, any show that embeds Come on Eileen in a scene is bound to be a winner. The funniest character on the show is Marmaduke, their crazy son.

If you are a Jimmy Kimmell fan (I used to love the Man Show), then you will also enjoy the videos that he has on there. Make sure you watch the Matt Damon video first (Again, not office friendly).

Last, but certainly not least, enjoy the stand-up of Demetri Martin. He is one funny comedian – I think I have watched this clip 10 times showing it to people.
