Sting Goes Full Cannibal at Malibu Karaoke Jam

Here's why you don't let Sting do karaoke at your bar -- he's SO DAMN GOOD ... he ruins it for everyone else ... and to prove it, TMZ has video of his impromptu rendition of "She Drives Me Crazy" by Fine Young Cannibals this week in Malibu.

Sting grabbed the mic Wednesday night at a place called Cafe Habana, where he performed the 80s classic smack in the middle of the packed bar ... and he nailed it. It's actually really cool to watch.

And now, the best rendition of "She Drives Me Crazy" ever recorded ... by the Muppets.
