Had a colonoscopy recently because I'm 49 and my mother had colon cancer.
I was nervous about being put under. During prep, the medical professionals would ask what I do, and I wasn't sure what to say. I told them I used to be a video game programmer, but now I'm a househusband. The answer was complicated, and in retrospect, they were more interested in making me comfortable rather than actually knowing what I do for a living.
BUT... also in retrospect, I realize they would soon be pumping air into my unconscious hairy butthole and hearing all sorts of sounds come out as the air they pump in escapes.
I'd like to imagine that the reason they ask me about my job is that they then get to have fun making some high powered executive fart musical anthems.
Note to future self: I am supposed to go in for another colonoscopy in 5 years. If they ask what I do, I will tell them I am a professional dad specializing in fart jokes. I will then ask them if they know any good fart jokes.
