Guys, I will probably chicken out and not go as him anyway, but I think maybe you are thinking too much into this. I forget sometimes how much time I spend on the internet compared to a lot of people, and I personally know people who only just came upon the Chuck Norris meme an find it hilarious. There are also people out there who don't know who he is, y'know? This was a thing that came up in gabbly (I think the conversation was something to do with the worst idea for a slutty costume) that I found hilarious, because it would be so terrible. I am going to see a band who in their music videos dressed up as evangelists and busked in a mall to their song, did skydiving in tuxedos, and staged a skipping competition based in the 80's wearing matching tracksuits. If I make someone laugh that night it will be worth it.
But like I said, I probably won't wear the costume, especially if it takes too much effort to get everything ready in time.
