I don’t think they’re immune at all. I’ve done it at least three times.
One time I was having a problem with persistent itching, down—you know—yes, there. The doctor asked me if it was inside our outside. I said, “Inside what? Outside what?”—because there’s a lot of ambiguity in that area, if you ask me. And he sort of stammered and didn’t answer the question. That one amazed me. He shouldn’t have been at a loss for words.
Another time I got the giggles something awful at the dentist’s office (this was before they were all worried about AIDs—he wasn’t wearing a mask). Every time he bent over me with his instruments, I started laughing again. I couldn’t help it. I was just giggling out of control. It was because I kept thinking about how I was looking up his nose. I thought it would be fun if there were a little TV in there that I could watch while he worked, and the more I imagined it, the funnier it was. I couldn’t help myself. (I was a grown woman, probably in my 40s at the time.) He was getting more and more perturbed, and finally he demanded to know what I was giggling at. I didn’t want to tell him . . . but he insisted . . . and then he turned beet red, and I was really sorry. He called his assistant over and made me tell her too, and she started laughing. Unfortunately that didn’t fix me. It just made it worse. I tried really, really hard to get it under control, but he did have to keep stopping work every time I broke up again. Forever after, I couldn’t look at his nose without having to kind of suffocate myself.
The third time was just recent, and I should have behaved myself better, but the devil ran away with my tongue. The dentist (a different one—wonderful man, a genius, and I love him) was talking about what would happen if my tooth got infected after he worked on it. He kept talking about pus (yuck) and went on and on about what if it got all pus-y. Finally I asked him how he spelled that, and he said “P-u-s-s-y.” So then I asked him how he pronounced that. He stopped, blushed, and then ignored the question. Naughty me.
