The original Handsome Dan is stuffed and mounted. He's on display in one of the trophy rooms of the Payne Whitney Gym on Yale's campus.

Yale still has a Handsome Dan. As the mascot bulldogs get too old (or too dead) to attend football games, a new one is christened with the name.

I like Improv Everywhere's early stuff when it was small and just surreal. The later stuff (yes, as featured on This American Life) and this one are invasive, intrusive, and annoying.

They're not entertaining everyone else as much as they are entertaining themselves. To do so, they (the organizers at least) take a view that their prank will obviously be fun for everyone. If you are a target and you don't have fun, then you didn't get the joke or you're just boring.

If the kids enjoyed it, then great, I'm glad for them. But this doesn't make IE's pranks smart, funny, or entertaining if you're the target.
