i guess i understand the goal of a show like The Big Gay Sketch Show, to provide comedy that is oriented specifically toward gays and lesbians, but i gotta say, i think Mad TV already provides that. ever since Comedy Central started screening massive amounts of it and i was forced to watch, i've been down with Mad TV. i think the show's lower profile (compared with SNL) allows it to be more experimental, and more outrageous with its comedy. of course it hits quite off a lot of the time, and i think the repeating characters are the worst part of the show.
when i was younger, i remember thinking that the show was offensive to minorities because of some of those repeating characters. but now i think they might actually be making fun of the stereotypes, a trend that has become increasingly common in mainstream comedy. i don't know. what i do know is that they have a lot of sketches about lesbians that i've always found extremely pro-gay.
examples- a remake of the mary tyler moore show where she realizes she's a lez and comes out to the newsroom, and turns out she's dating rhoda. a girl who brings home her girlfriend to introduce to her parents, but they are ridiculously in denial and manage to straightify everything she says to them. a man convinces his wife to have a threesome, but turns out the threesome lady is really butch, so the man is turned off, but the wife is verry into it.
it seems like they've almost consciously not made fun of lesbians, especially considering they've got a reputation as a white trash show. cool.
