Ellen Pompeo Gets a Scare for the Second Time on 'Ellen' (VIDEO)

One of these days, Ellen DeGeneres is going to give someone a heart attack, and it might just be Ellen Pompeo of 'Grey's Anatomy.'

On 'The Ellen DeGeneres Show' (weekdays, syndicated), DeGeneres scares yet another guest during an interview. This time, a man in a zebra costume slowly creeps up behind Pompeo and gives her a fright, causing the actress to shriek and recoil in her chair.

DeGeneres then tells Pompeo she's the first person who's been scared twice, and Pompeo can't help but congratulate the host on her ability to freak her out.

"You're really a great actor," Pompeo said, adding that she fell for the scare even though she "knew it was coming."
