Gay bars are always absolutely full of women. Attractive women, too. You know why? They're hiding from the straight men. It's pretty obvious when you think about it.
Woman 1: I wanna go out and have fun without dealing with creepy guys hitting on me all night. Where should we go?
Woman 2: Gay bar!
Meanwhile, across town...
Brodude 1: Dude, bro, I wanna score some chicks!!! Where should we go?!
Brodude 2: I'll tell you where we shouldn't go, bro! Dude, we should totally avoid the gay bars. It's like, total sausage fest, bro! And all the women there are angry lesbians!
Brodude 1: Dude! Great idea! Pass the Axe Body Spray!
