Ben Affleck and Ellen DeGeneres play a game of "Lap It Up" on 'The Ellen DeGeneres Show' (weekdays, syndicated), competing to see who can build the tallest tower of blocks on a person's lap in 45 seconds.
DeGeneres takes the lead early and maintains it throughout the competition, resorting to a ladder when her stack becomes too high. Affleck, meanwhile, struggles to keep his tower from falling over.
Eventually, both towers collapse and hit the people they were being built on squarely in the head, but not before DeGeneres clearly bests Affleck. She's gracious in her win, though, and declares the competition a tie.
