We have watched Ellen DeGeneres terrify celebrities with prank scares long enough. Let's take a stand by continuing to watch these scares and praying it never, ever happens to us. Because I would not react to Michael Myers jumping out of a box with the grace that Lea Michele exhibits here.
It's down to Taylor Swift and Richard Simmons for best all-time scare. Though Richard Simmons is in a perpetual state of terror, so maybe Taylor takes the win.
