Seth Rogen and Joseph Gordon-Levitt set aside bromance to share barbs on 'Drop the Mic'

Longtime 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.
