I'll go as far as saying that certain roasters of the inbred redneck were pretty damn funny, especially ross, diPoalo, Giraldo, and Busey. But overall, the Saget Roast, the Leary Roast and Shatner Roast were all much better as roasts.
The Pam Anderson one turned into a reality show, the Flava Flav one was the same sh-- over and over, with Flav completely !@#$ed up the whole show. Frankly, they just don't compare to the ones mentioned in the previous paragraph.
I'd like to see them roast people like Robin Williams, Steve Martin, Eddie Murphy, Adam Sandler, Jim Carey, etc....
