I don't have time to do a detailed post with a perty picture today. Instead, I'm giving you an activity.
Spend a few minutes (or days) on http://failblog.org/ perusing the world's pranks, mistakes, and general "fails." Then spend the rest of the day being extra observant for the fails that might be around you all the time. Document them and submit them to failblog so everybody can enjoy and learn from somebody elses misfortune.
