The show was Beverly Hills 90210. One of the regular dudes landed a part as the pizza boy in a porn movie. They start the scene with no rehearsal, the producer insisting on a first take. The guy rings the bell, 2 gorgeous babes, a blonde and a brunette both greet him at the door and lead him over to the couch where the 3 of them sit down with the guy in the middle. This all happens too quickly but it was intense. The girls are putting their hands all over his torso while he is holding the pizza in his lap. He is of course very ticklish, and starts laughing and squirming uncontrollably, telling them, “Stop! I’m ticklish!” Of course they don’t stop, but rather dramatically increase the intensity of the tickling. He thrashes about, violently enough to dump the pizza, face down on the floor. “CUT!!” the angry director yells. This incident gets the guy fired from the part. A brief but very cool television scene.
