This reminds me of an absolutely true story. I was sitting in a meeting once long ago at a clinic I worked at in the 70s. There was a whole room full of people there and suddenly and unexpectedly someone asked a woman present there where she got the nickname "Butters". Well, everyone was a little shocked because I think we had all just assumed it had something to do with the woman's weight, which I would estimate at around a deuce, deuce and a half. I'm sure everyone just assumed it was a take off of "Butterball" or something like that, but of course nobody ever talked about it. Then suddenly, in the middle of the meeting, some doofus blurts out "Hey Butters, how did you get that nickname anyway?" "Whooooa, what a jerk", we are all thinking, but without batting an eye Butters says "It's short for 'Butterfly'" and she was dead serious. Er? You could hear a pin drop in there for what seemed like a very long time. Then doofus says something like: "uh.. gee. I woulda thought; ya know; like; butter... um... it's sort of soft and like, ya know and stuff. Butterfly, huh? Nice name." Bruce
