Late night TV host Jimmy Kimmel turned 50 yesterday, so in honor of that milestone, a bunch of celebrities turned the table on Kimmel and read mean tweets about HIM. Normally, it's the other way around and the celebrities are reading mean tweets about themselves, but not this time! So watch below as Ray Romano, Halle Berry, Tracy Morgan, David Letterman, Stephen Colbert, Howard Stern, David Spade and many more roast the birthday boy on his special day!
