If you know anyone who drinks Diet Coke, they need to be worried tomorrow. It's an easy prank. How would you like to be friends with Prank King Jimmy Kimmel? Jimmy had on Mark Rober, a former NASA worker, who now has his own youtube channel, stopped by to show off some hilarious pranks. The coffee cup looks doable. The backup camera had me laughing very, very hard. Enjoy. Beware!

I like these pranks because they don't go too far. Some of the internet videos are just wasteful. I can see actually pulling some of these off and NOT ruining friendships.

It's Christopher Walken's 73rd Birthday today. Some of my favorite work of his was done on Saturday Night Live. Not just cowbell but this classic Pranksters!
