Ellen DeGeneres Scares David Spade -- Again (VIDEO)

You can fool some of the people all of the time, and all of the people some of the time, but you can't fool all of the people all of the time. Unless you're David Spade. On Monday's 'The Ellen DeGeneres Show' (weekdays, syndicared), DeGeneres played a clip of a past show in which she brought out an assistant dressed in an oversized dog costume to scare the heck out of an unsuspecting Spade. "I get scared easy," he said. "Don't do it again." "I won't," DeGeneres said. Then she took Spade to a table with a big cake on it. We smell set-up!!!
