The Ellen DeGeneres Show celebrated its 2,000th episode last week, and in honor of the milestone, the host put together a hilarious montage of her favorite scares from over the years. In addition to Taylor Swift [1]'s memorable fall in her dressing room, Ellen has made Halle Berry [2], Dennis Quaid, Justin Bieber, Emily Blunt [3], and Carrie Underwood [4] all scream like little kids. Watch the amazing montage video above, and then check out One Direction playing a revealing game of Never Have I Ever with Ellen [5].
