12. Margaret Cho on keeping an open mind

Margaret Cho endorses taking a lick from the pansexual buffet, advising, "if you have not had sex with women before, you should try it, like, one time." A minute-long pantomime of a gay man eating pussy ensues. Cho makes us believe in physical comedy again.

11. Bill Hicks on blowjobs

Bill Hicks is famous for genius bits about politics, spirituality, and smoking. But he was an equally insightful observer of the smaller things in life. Watching him mime an unenthusiastic blowjob is funny enough to temporarily make you forget that this man was equally concerned with the Kennedy assassination and finding a god within yourself through hallucinogens.

10. Rodney Dangerfield on his marriage

Rodney Dangerfield's entire schtick is so archetypal at this point that it's hard to remember quite how sharp it was. But he had self-loathing and marital boredom honed to a razor-sharp point, as this classic clip shows.

9. Joan Rivers on advice for our daughters

Joan Rivers performs great stand-up, but she also offers solid advice to all mothers. She implores them to tell their daughters this: "When you get old, your vagina's going to drop, but it's a good thing, because you can have sex in the bedroom and still be watching TV in the living room." That's wisdom.

8. Robin Williams on Viagra

Watching Robin Williams work through a bit can be exhausting; he rarely stays in one voice or personality for more than one line. But that's the charm of watching him careen through this bit about Viagra — there are more jokes per second in here than there have been in Dane Cook's entire career.

7. Sarah Silverman on having sex without crying

Sarah Silverman's tactic of delivering incredibly foul-mouthed, blue material in a baby voice is polarizing, to say the least, but there's no denying the rock-solid construction of her jokes. This clip finds her launching into an elaborate musical number about porn stars. The coal-darkness of a line like "Do you ever take drugs so that you can have sex without crying?" is leavened, like the rest of Silverman's material, by her incredible voice and delivery.
