What do Joel McHale, Kristen Bell, Louis C.K. and Roseanne all have in common? They're all celebrities, yes, but along with that they also receive some of the meanest tweets from strangers on a daily basis.

On Wednesday night's "Jimmy Kimmel Live!," Kimmel celebated the 6th anniversary of Twitter by having his celebrity friends read the least flattering things ever said about them on the site. As you can imagine, some of them are pretty cutting while others are just confusing.

David Cross gets a "not my kind of comedian" comment, Will Ferrell gets called "Dum" (while he's sitting on the toilet, no less) and Will Arnett can't quite wrap his head around why people think he looks like Dracula. As a bonus, all the tweets are read with R.E.M.'s "Everybody Hurts" playing in the background for maximum sadness.
