Today I went to an informal lunch meeting where there were going to be several gay Microsoft employees in attendance. I thought of how I was going to introduce myself, and this is what I came up with. Unfortunately a good opportunity never really arose so I never got a chance to use it.
"So anyway, I recently decided to become gay mainly for the health benefits. I haven't really noticed any improvement in my appearance though. Maybe I'm just doing it wrong." Assuming I couldn't quite keep the deadpan look, I'd then follow up with "Sorry, I just couldn't tell that joke with a heterosexual face."
