This Is The Funniest MMA Knockout Of 2013

Derrick Mehmen landed a shot on the side of Rolles Gracie's face that didn't seem particularly brutal in the second round during Saturday night's World Series of Fight 5. Oh, but it was.

It actually looked like Gracie was going to walk it off, but then he kept walking, and probably muttered something like, "I don't feel like punch anymore," before crash-landing on the mat.
