Seth Rogen and Joseph Gordon-Levitt hit below the belt on 'Drop the Mic'

Long time friends Seth Rogen and Joseph Gordon-Levitt didn't pull any punches when they went head-to-head on Drop the Mic. The two actors played best friends on 50/50, but on this night they were spitting venom at each other. Gordon-Levitt immediately went after Rogen's portly physique. He rapped, "You're fat, sorry, I'll just say it plainly I mean, you're not orca fat, you're not insanely overweight just too many snacks and doobies but enough so you can't really be in action movies. Got to diet, man, or try a juice fast or at least just stop eating James Franco's a**." Rogen had the perfect comeback to Gordon-Levitt's afront. He rapped, "I'm chubby, I'm balding, I'm lazy, I smoke pot, so tell me, how am I a leading man and you're not?" In the end Gordon-Levitt was crowned the champion and everyone went back to being nice to each other. Drop the Mic airs Sundays at 10:30 p.m. on TBS.
