Ellen DeGeneres continued to be America's cool aunt by pulling a few pranks on America's hot cousin, Carrie Underwood. This was the singer's 10th appearance on the show, and the two reminisced about her first appearance 10 years ago. We were babes—just little babes," said Underwood. "Right after Idol, I was on it."

To celebrate this milestone, Carrie got pranked a couple times, because Auntie Ellen loves her some pranks! Here's prank number one, which involved Seth Rogen (who appeared earlier in the show) and Carrie's "famous chicken dance."

And here's prank #2, which involves Ellen surprising terrifying Carrie with a gift to "celebrate" her 10th appearance on the show.

The dude who jumped out of Ellen's side table is wearing a Mike Fisher jersey (Carrie's is married to hockey player Mike Fisher).

Carrie was so shocked she screamed. C'mon, Carrie, when you're friends with Ellen, you must always be on high alert for pranks. Take it from me, someone who has been BFF with Ellen for years in my mind. She could be pranking me any day now, so I always stay vigilant.
