Brock Lesnar is an MMA superstar right now and just came out with a brand new book called Death Clutch.  So he went onto Late Night with Jimmy Fallon to talk about that, his involvement with the new season of Spike TV's Ultimate Fighter and ultimately ended up putting Jimmy in a sleeper hold.At first I wasn't a big fan of the whole mixed martial arts scene, but since last year I have been turned thanks to my friend Kevin constantly watching it.  He got me into it, and I am grateful.  It's like watching Gladiators in the arena at Rome, minus the whole death thing.  Check out this video of Brock Lesnar on Jimmy Fallon last night.  Very funny stuff.  Fallon continues to be the late night standard.
