Hmmmmm. Here's this week's Moment of Stupidity:

Talk with friends for the 1000th time about going to Cirque du Soleil. Decide to take action and organize a group to go. Ask lots of friends if they can go. Have difficulting finding a day when everyone can go. Finally, this morning, we find a night that everyone can go - tomorrow night. I buy the tickets. Two hours pass. A friend emails me and reminds me that we're going to a concert on that night.

Whoops.
