The Ellen Degeneres Show and pranks

When you have a talk show you absolutely have to have something funky / daring to do to your guests. I remember Marc Labrèche slipping his guests off his show The tall blond with a nickname show (The intro is so nice, I couldn't even remember it being that good). Ellen Degeneres's concept is to scare her guests with mascots. I still really like the idea, and here is a montage of the best reactions.
