Bronson Pinchot and Mark Linn-Baker accidentally injured each other while filming the scene where Balki shakes Larry back and forth. Linn-Baker had a gash in his forehead and Pinchot's tooth was pushed back up into his soft palette, but they were cleaned up in less than fifteen minutes after the crew carried them out and they finished the show. They even did a Q&A session despite the injuries they sustained.
When Bronson Pinchot and Mark Linn-Baker were taken to the emergency room after the show to have their injuries treated, fans bothered them for autographs.
