Get ready for some Nip/Tuck punchlines, folks. The line-up of tormentors has just been announced for Comedy Central’s Roast of Joan Rivers. The legendary comedienne/Apprentice champ/plastic surgery cautionary tale will take her turn on the dais when the show airs on Aug. 9 at 10 p.m. ET., and we have a feeling that the prick of a Botox needle will probably seem painless compared to the delightfully filthy barbs administered by Roast Master (Roast Mistress?) Kathy Griffin.

Joining Griffin in the dirty-joke dogpile are: Everybody Loves Raymond/’Til Death‘s Brad Garrett, old-school icon Carl Reiner, and nervous nebbish Gilbert Gottfried, as well as Jeffrey Ross, Lily Tomlin, Mario Cantone, and Richard Belzer. In other words, it’s gonna get messy. Judging from the networks’ past roasts, the evening should be heavy on extended, multi-second bleeps. These folks like to work blue. And they’ll no doubt be at their bluest teeing off on Rivers — a dame who’s always been a master (mistress) of the ruthless put-down.

So which one of these roasters will land the best — by which we meanest — plastic surgery joke? And where the heck is Lisa Lampanelli?
