don't know if this was ever pointed out, but I'm pretty sure Eminem is the originator of the young money punchline set up, the one Big Sean claims to have invented. this is all the way back in 2000 on MMLP's Who Knew, eminem goes: "My Life's like, kinda what my wife's like. fucked up after i beat her fuckin ass every night, Ike" .
if anyone can find an earlier instance, tell, otherwise Em is shortchanged on his influence on hip hop (again).
