It's August, so you know what that means: Time for Comedy Central to roast another D-list celebrity!

The network chose comedian Roseanne Barr, who helped pave the way for female comics with her sitcom Roseanne, which ran from 1988-1997. And fellow comic and self-proclaimed "king of roasts" Jeffrey Ross wasted no time stirring up trouble. According to The Hollywood Reporter, he showed up to the red carpet dressed as deceased Penn State football coach Joe Paterno, with a teenage boy on either side of him wearing nothing but a towel and a football helmet. His response? "If anyone has a problem, they can do what Joe Paterno did -- look the other way." Whoa!

When he showed up on stage, sans teenage boys but still dressed as Joe, he ripped into actor Seth Green. "You haven’t gotten this much attention since you shot all those people in Aurora,” he declared. When the crowd gasped, Jeffrey continued. "“I’m kidding!” he said. “You’re not like James Holmes. At least he’s doing something in a movie theater that people remember.” That joke was met with a mix of boos and light applause.

At the end of the show, Roseanne made it clear how she felt about the jokes. “That crossed the line,” she said. “But comedy is about moving the line. And where is the line in a country that has freedom of speech? Maybe there isn’t one.”

Dane Cook attempted to make a joke on-stage about the Colorado shooting three weeks ago before apologizing for his actions. However, Jeffrey has said he will not apologize for his jokes. We wonder how this might affect his new Comedy Central show The Burn, which premieres next Tuesday.

UPDATE: Producer Jonas Larsen said Ross' jokes about the Aurora shooting will not be a part of the telecast when it airs on August 12.

What do you think about Jeffrey's jokes? Funny, too soon or never okay?
