snl in class

yesterday i showed best of snl dvds (in english, no subtitles) to two classes: dana carvey to one, and will farrel to the other. it was a little embarrassing sometimes when they used terms like: "kibbles and bits" hanging out of your shorts; linda trip totally "cock-blocked" slick willie; or i can see your "bulge." but i stand firmly on the belief that english teachers ought to know slang, not just formal english, and that college students are certainly old enough to study such topics. though i must admit i'm rahter glad nobody interupted the movie to ask "excuse me, what does 'cock block' mean?"
