I joke I joke, I kid I kid.

Guy: What's the latest Eminem song?
Me: Ass Like That
Guy: You mean like yours?

I was holding a single entitled "Do I look like a slut" when he asked that. I'd been showing it to coworkers who ask why I laugh all the time, and for no apparent reason. I tell them it's occurrences and song titles such as the above described that parade through my head endlessly and cause me to laugh while my boss is instructing me to do something completely not funny. "Colleen has an entirely preconceived internal dialog running each time she looks at someone" is how my supervisor put it.

I think it's a combination of a couple mental illnesses.
