I had a coworker who was a self-proclaimed juggalo, and was bragging about it while I was working beside him, trying to bite my tongue... however he said something so profoundly stupid I couldn't hold it in anymore. He said, "According to the FBI, we are the third most dangerous gang in the US." I turned to him and said, "Yeah well you can't even wrap your heads around magnets, so I think we're going to be just fine." He didn't approach me with hobbies much after that.
