Here's one rap battle we didn't quite see coming. It seems that 50 Cent, who in the past could be found in da club with a bottle full of bub, is now dedicating his time to more serious enterprises. Namely, stopping P. Diddy from exploiting the Notorious B.I.G.'s memory. Fiddy recently launched a Twitter petition (Twitition!) imploring fans to give their digital John Hancock in an effort to ban Puffy from using Biggie's legacy to further his own career. It seems Half Dollah became incensed by the video for Jay Electronica's "The Ghost of Christopher Wallace." (which features Diddy.) 50's petition tells readers, "Enough is enough, Biggie's name should never have become Diddy's Black Card." Which is actually sort of clever. There doesn't seem to be any real explanation of just what the petition is supposed to accomplish, short of shaming Puff Dizzle into retirement (in which case, he could cameo in more movies, dude was amazing in Get Him to the Greek, seriously) but if you feel compelled by the cause: sign here.
