Brock was MUCH better behaved than this last night.
For the convenience of our readers that reside outside of the US, I've embedded an unofficial upload of Brock Lesnar's appearance on NBC's Late Night With Jimmy Fallon last night to plug the premiere of The Ultimate Fighter 13 Debut and eventually UFC 131, where he fights opposing coach Junior dos Santos. If you're in the US, the official version is available on Hulu.
Anyway, it's a fun short interview. Fallon starts by plugging Brock's book "Death Clutch: My Story of Determination, Domination, and Survival" (due out in about two months) and The Ultimate Fighter Season 13, which Brock explains the concept of. Brock is in full Polite Brock mode, even coming as close to admitting that he made a huge mistake by getting as close to admitting that he may have made a mistake by getting a phallic object tattooed between his pecs. He also teaches the rear naked choke to Fallon. Fun short fluff interview.
