In 'Stop the Clock', Bert is trying to have a game of baseball with Bentley. He throws a ball towards him, and what does Bentley do? He sits down at his computer, calculates the precise point the ball's going to land at, and simply places his hand at that point. His calculations are a bit off, however, and the ball hits him on the head instead...before landing in his glove.
Arguably, the grunt of pain he gives when the ball hits him in the German dub of this scene could be considered pretty funny.
