People who deserve the roast more than Sheen.
There are so many people who deserve the honor more than this tabloid has-been junkie. Aren't roasts supposed to be reserved for legends?
Here would be my picks:
Comedians
Louis CK
Chris Rock
Jerry Seinfeld
Dave Chappelle
Bill Maher
Eddie Murphy
Jeff Ross
Jon Stewart
Lewis Black
Ricky Gervais
Betty White
Gilbert Gottfried
Other Legendary Entertainers
Robert Evans
Will Ferrell
Mel Brooks
Samuel L Jackson
Matt Groening
Robert Deniro
Hulk Hogan
Sean Connery
Chuck Norris
Stan Lee
Kevin Smith
Arnold Schwarzeneggar
Obviously not all roasts would be of the same caliber, but at least it would be better than picking out tabloid d-bags.
