Justin Bieber was technically the star during the taping of his "Comedy Central Roast" last weekend, but there was also a runner-up: Bill Cosby.What else did you think would happen when you get a bunch of comedians in a room together? In the months following Cosby's downfall after dozens of sexual assault allegations against the 77-year-old comedian, there have been plenty of jokes at his expense -- including the memorable "Sleeping Beauty" jab at the Golden Globes from Tina Fey and Amy Poehler.
