Has all kinds of videos there - quality isn't always great..
Some topgear stuff there as well...
A quick word of warning...I checked out one video called something with fight about car - or similar...and although I do be watching a lot of nasty stuff as part of my job (not kidding!)...this is extremely violent...and definately NOT recommended viewing..doesn't matter what you've seen before - it's just plain wrong..
There is LOADS of entertaining stuff though..
Some stand up
Some Rally clips
Some Generally Naughty stuff
Russians being incapable of driving on ice..
Hours of entertainment...
