One of Ellens favorite things to do on her show is to scare her guests, and her latest prank involved Justin Bieber and the Womens bathroom on the set of her show.

I love the fact that Ellen loves scaring people, my favorite segments are when she send her producer on the haunted house exhibits, but I gotta say this one made me laugh out loud a few times. My favorite scenes are when they pretend to be making out, and when Ellen is sitting with a mask on playing a clarinet. Epic!
