Tina Fey knows the difference between male and female comedy writers: One pisses in cups, the other uses maxi pads.
The New Yorker has run a second excerpt from Tina Fey's upcoming book, Bossypants. It contains the line (also used in her Kennedy Center speech), "Only in comedy, by the way, does an obedient white girl from the suburbs count as diversity." Fey is clearly both tired of having to explain why she's the only woman in the room and just plain tired of being the only woman in the room. So instead she talks about jars of piss, which she found in more than one male comedy writer's office.
Not all the men at "S.N.L." whizzed in cups. But four or five out of twenty did, so the men have to own that one. Anytime there's a bad female standup somewhere, some idiot Interblogger will deduce that "women aren't funny." Using that same math, I can deduce that male comedy writers piss in cups....
To continue with this science of broad generalization, pissing in cups may show that men go into comedy to break rules. Conversely, the women I know in comedy are all dutiful daughters, good citizens, mild-mannered college graduates. Maybe we women gravitate toward comedy because it is a socially acceptable way to break rules.
Incidentally, the most prominent exemplar of "why women aren't funny," wasn't an Interblogger, but a celebrated Vanity Fair columnist. But Fey's point about good girls and misbehaving boys strengthens her other point about the gender gap in comedy, which is the gap in frames of reference.
