We had a similar dumb fuck a few years ago. My work was based in LA but we had a small satellite shop in Vancouver. There was always a rivalry with them for some reason because they always acted like they were better than America. Healthcare or some such nonsense for another discussion. So it is about 2005 and we have a Halloween party. One of the Canadian guys shows up in a costume with his hair slicked straight up, and his tie made to go straight up. He was a 911 jumper. He was very smug about it as well.
I was a few drinks in and I was training Muay Thai 7 days a week at the time so I was a little more aggressive than normal. Long story short… he took the costume off.
