I hope this is an antiquated practice now, but back when I was a little wide-eyed first year, our histology lectures were recorded on tape. Then to study, we'd go to someone's house who had a VCR and watch them over and over and over until our eyes would bleed.
It was horrible.
Anyway, I was at one of these "histology parties" in my second term of med school at a friend's house. One of the people present was a young guy named Angelo, who was one of those people you look at and think, "He seems really cool." He was funny, always seemed to have a lot of girlfriends, and on his way in to the histology party, had accidentally gone to my friend's landlady's apartment and after declaring her a "MILF," claimed he considered ditching the party and staying with her.
Anyway, somewhere in the middle of watching tapes, Angelo spoke up, "Hey, what did everyone get on the practical portion of the anatomy final?"
Nobody volunteered a score, so Angelo said, "I got three wrong. I'm just wondering because I think I may have gotten the highest score in the class."
Immediately, I thought, "Wow, that was obnoxious. What a total gunner."
But later, my friend (who was also Angelo's lab partner) told me that Angelo "wasn't like that." That he was just genuinely curious about whether he got the highest score in the class. And that if he got a low score, he would have asked around to see if he got the lowest score in the class. At the time, I totally bought it.
A couple of years later, my roommate who was on a rotation with Angelo told me that he was the biggest brown-noser she had ever seen. She came home every day with ten stories that made her want to strangle him. Then he was junior AOA.
So the moral is, if someone acts like a gunner and talks like a gunner, don't kid yourself. You're looking at a gunner.
