In reply to Fly Fifer: Well, this may be too leftfield, but, dead undead, purely because it may be the worst film ever made, and it has luke or matt goss in it. I can't remember which. Its comedy gold.
The boondock saints pt 1 and 2, just for Billy Conollys Irish accent.
Dead snow
The Blood Rayne trilogy.
They are not the A-typical comedies, I understand that, but they amuse me.
The Ricky Gervais show is definately worth a watch, as is An Idiot abroad.
Book wise, try the "merde" series by Stephen Clarke
Also "The gates of hell" by John Conolly, quite funny for a kids book
I'm sure I'll think of more
