I don't think this song is nearly as bad as most of the other silly shit from Encore. The beat is a classic and unbelievable through a subwoofer. The song is a bit of a mess but I find it so catchy with some hilarious lines throughout.
It's obviously not up to the standards of most of Em's stuff but I think it's actually a stand out track on Encore.
I know this track is pretty much despised by most but I've seen some calling it the worst Eminem song ever which just makes me laugh
