A girl brings a guy home one night.
They get into her apartment and immediately she suggests that they do "69".
"What the hell is that?", asks the guy. Realizing he's inexperienced, she tries to explain, "I put my head between your legs and you put your head between mine."
Still not knowing what she's talking about, but not wanting to ruin the moment, he agrees to try it.
The second they get into position, she lets loose a rip-roaring fart.
"What the fuck was that for?...." "Ooops!...sorry, let's try again" she says.
So, they get into position again and......once more she lets one loose!
The guy gets up and starts to put his coat on
"Wait, wait, where are you going??" she asks.
The guy says, "If you think I'm sticking around for 67 more of those,
you're crazy!!........."
