19. Lisa Lampanelli
Lisa Lampanelli shtick is so notorious, she's known as “The Queen of Mean.” Her stand-up routines are fixed around insulting as many people as possible, with Lampanelli making un-p.c. remarks about race and homosexuality. For instance, here's Her Highness joke riffing on Rihanna and Chris Brown during Comedy Central's roast of Larry the Cable Guy: “You've beaten that concept so hard it's now dating Chris Brown.”
Lampanelli’s appearance on Celebrity Apprentice early last year wouldn't go unremarked upon either. The apologies were demanded of her, she refused to offer a mea culpa for using racial slurs during her stint on the series.
