So this is a real thing that occurred during a match: CM Punk decided to go all Mike Tyson on Brock Lesnar during their match at WWE SummerSlam last night (Sun., Aug. 18, 2013) in Los Angeles, and bite his ear. He bit his ear. Really enthusiastically, I might add. Sources tell us Lesnar's doing just fine, though. GIF via SB Nation. If the GIF won't animate for you, click here.
