For the sake of comedy, Roseanne Barr will get dirty. The former sitcom star has invited controversy her entire career, most memorably in 1990 when she performed a rendition of “The Star-Spangled Banner” before a Padres game in San Diego. During the performance, she deliberately sang in a loud, grating tone, and afterwards, she made a point to mimic baseball players by spitting on the ground and grabbing at her crotch.

Off the diamond, she’s called Israel a “Nazi state,” and—though she does support same-sex marriage—has used a variety homophobic words, mostly in the early '90s, as insults. Makes the fact that she ran for president under the Peace and Freedom Party more than a little ironic, doesn’t it?
