Anyway, one day a few of us (both boys and girls) were hanging around in the neurology residents office, bullshitting about random stuff while we waited for rounds to start. Dr. Tree was at his desk, reading some neuro textbook and ignoring us.
At some point we began joking about porn. I have no idea what led to that. This went on for a few minutes, when suddenly Dr. Tree slammed his book closed, came over, and yelled the following diatribe at us:
"You think it's funny! It's NOT funny! The problem with porn is that it gets so out of control! You start with a dirty magazine, then you move into books and movies. You keep needing more and more, and the tame stuff isn't good enough anymore, so you need filthier and filthier, harder-core stuff! It's like a snowball rolling downhill, and YOU CAN'T DO A FUCKING THING TO STOP IT!"
Dr. Tree abruptly stopped and turned red. The rest of us, somewhat taken aback and unsure what to say, looked at him silently.
After a pause he mumbled "Um, at least that's what I've heard."
He picked up his book and ran out of the room.
