Streeter Seidell and Amir Blumenfeld have been pranking each other for years now, only their pranks are big-budget and seen by millions on the Internets, because Streeter and Amir work for CollegeHumor.com. You can find Streeter and Amir's full Prank War collection here. This time they've reached new heights, literally and figuratively, as the latest prank involved sky-diving, and also debuted on TV on ABC's Jimmy Kimmel Live. Streeter and Amir explained it all to Kimmel. Doing shots of limoncello with Danny DeVito is merely a bonus, right? But is their best effort yet? Well, there is the element of death involved. I don't know. I'm going to need some Axe body spray money to make up my mind. In the meantime, here is their TV appearance in two parts, followed by the full CollegeHumor version. Roll the clips!
