"Who's on first?", or, Denis Leary on Mel Gibson at a Red Sox game
Denis Leary brought his rapier wit into the Boston Red Sox press box when, delighted to learn the BoSox have a Jewish first baseman, he mocks Mel Gibson. Leary, who's a Massachusetts native, appeared as a guest to promote his charity which supports firefighters. He's the one in the yellow shirt.
Last I looked, the video is still available here.
For those unacquainted with baseball, Sandy Koufax, a Jewish kid from Brooklyn, NY, was one of the all-time great left-handed pitchers, and the play at the end of the video involved the quick-handed first baseman tagging the runner out at the bag.
