I came across Improv Everywhere in 2009 while searching for ideas for April Fool's day jokes. I stumbled on the site during the "Best Funeral Ever" incident, and loved it, watching all of the previous missions. Since then I've followed the group vicariously through the videos. I only wish I lived in New York so I could participate...

Getting people to laugh at life, and introducing the to something completely crazy is a wonderful thing to do. And mistaking their website for "Improve Everywhere" just makes it better.
