If you like prank calls, check this one out. It's around 35 minutes but it's funny as fuk. The whole prank is funny. The guy who's doing the prank call does like 4 voices on this one. it's really amazing. I think he's one of the best. His name is Blackout.
He calls this asian kid in Florida pretending to be Master Shredder. The rest is history.
