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!
