Back in the days when I worked a 9-5 job, I made it in after every Giants' victory. I was tired but I made it in. All my fellow Giants fans made it in too. One guy took off to go to the parade one year, but he used a vacation day.
I did take a pre-arranged day off one year. I had spent the weekend of the Super Bowl watching my nieces while their parents were at a seminar. They also had a Super Bowl party, so the girls and I got the house in order and I stayed to help the clean-up. So I knew it would be a late night, so I took a vacation day the day after.
