It's like the Thanksgiving of snack-binging. It's also a good reason to get together with friends and have fun. If you don't like football, then watch the commercials. If you don't like laughing, then snack and talk to people. If you don't like any of those things, well, I guess you're out of luck.
I took part in the Superbowl tradition long before liking football, and if anything I had more fun back then than I do now.
I didn't watch the Superbowl this year, though. Partly due to college homework, and mostly because I wasn't invited anywhere.
