Ellen DeGeneres celebrated Carrie Underwood‘s 10th appearance on her show with not just one…but two pranks! And since they are all caught on video, you get to enjoy them as well.

One of Ellen’s favorite things is to scare the crap out of people who stop by her show….Carrie Underwood is no exception. In fact, last year when she stopped by she was taken by surprise by one of Ellen’s writers dressed in a cowboy suit. When the “cowboy” came out of nowhere Carrie screamed, “Come on! You watch your back, people. When you’re here, you watch your back.”

Apparently she didn’t take her own advice, because it just happened again….

It seriously gets funnier every time!

Prank number two involves Seth Rogan getting Carrie to do her “famous chicken dance”…

Of course Carrie also took some time to perform her latest single “Dirty Laundry” as well.
