I was playing hockey a few weeks back with some new guys and at the end of the games, we started shooting the shit. I asked the goalie what he did for work: "I'm a doctor". "Oh cool, my brother is a doctor as well."

"Where?"

"<some hospital>"

"Oh, I work there as well. What department?"

"<the department>"

"Oh, haha, I'm a surgeon"

I lost it laughing.
