Anyone I know would feel it was his right as a full-blooded American to not do work on Superbowl Sunday.

Even though other people have weighed in on this, I felt I needed to go back and comment. I couldn't tell at first whether you were serious, and then I remembered the Super Bowl seems really important to great big masses of Americans.

My D&D group was meeting as normal. Someone suggested watching the Super Bowl commercials on Hulu, and several others didn't know the Super Bowl was happening that day. (Personally, I had to skip D&D to work on my dissertation).
