MC Hammer recently decided the best way to rekindle his once massive flame was to start a beef with Jay-Z in the way of diss track called "Better Run Run," boasting lines like, 'That boy tried to steal my swag/His finger prints all over the bag." While it might have sounded good on paper -- start beef with Jay-Z, video goes viral, Hammer is back on top -- the gesture has kind of backfired. Jay-Z didn't have much of a response to the whole thing, other than saying that he had no plans to respond with a diss track of his own. Too bad. It would have all been like David and Goliath -- well, if David had once worn parachute pants and rapped to kids, that is. Click through for a list of five other monumentally stupid beefs.
