Ellen DeGeneres Terrifies Taylor Swift

Set up fake dressing room and hidden cameras. Crouch down and hide in the corner. Scream and scare the living crap out of guest. Talk about a winning formula!

Ellen DeGeneres got into the Halloween spirit this week, and while her tactics were neither super original nor elaborate, the results are still hysterically funny.

Here's Ellen scaring Taylor Swift in the manner described above ...

Taylor Gets Scared

LOL. We don't know what it is, but there's something about watching Taylor Swift react like she did which just makes us love America's Sweetheart even more.

Follow the jump for Ellen punking more celebrities in similar fashion. What's not to love about Mario Lopez, David Spade and Lauren Graham getting spooked?

Oh, and after the producers decided to turn the tables on Ellen, Jimmy Kimmel gets an award for chivalry for racing to her aid (and being quick on his feet) ...
