To bring some seriousness to this subject I would nominate Sherri Shepherd. She is the heavy-set black woman who appeared on the sitcoms "Less Than Perfect" and "Everybody Loves Raymond" (she played Robert's partner on the police dept.) Noone else I have seen comes close. And speaking of ELR, I would nominate Patricia Heaton, who played Debra. I don't think she ever guest hosted, but they are going to need two hosts once Rosie O is gone. Thank god.
