Michael Stipe, "Twat Waffle"

The R.E.M. frontman has been allegedly been dubbed "Twat Waffle" by Sara Barron, a former waitress at a trendy New York restaurant who claims - in her upcoming memoir People Are Unappealing - that he and his posse rang up a bill of $2000 and left no tip after dining for over five hours.

Allegedly, he wouldn't talk to the waitress either, instead delegating one of his 19 hang-ons to make the demands. He may have lost his religion a long time ago, but the guy could use to learn some manners.
