Playing UFC undisputed 2010; in one match when I initiated the clench the fighters began to be pulled apart slowly by their feet while still trying to hold onto one another. It looked like they were being sucked into black holes on opposite sides of the screen. Once they had been pulled far enough that they were no longer touching, but still reaching out to each other with all of their might, they began to shake, convulse, twist, and flop around in grotesque, impossible positions.
