I am a huge fan of Conan on TBS. One night, he had a British comedian on that had me rolling with his bit. I have watched the video many times since and it's still funny.

This comedians name is James Veitch. This bit alone is worth checking him out further.

He is a British comedian known for his Youtube show Scamalot where he pranks those that send scam emails. Here's one example of his work.
