From the entry on the awesome, Israeli/summer camp sport ga-ga, we learn this about Ali G/Borat:
The comedian Sacha Baron Cohen, despite his lanky frame, was noted for being a champion ga-ga player in his Habonim days. According to his official online biography, Cohen won the Habonim UK ga-ga championship on multiple occasions and in 1992 led his country to a silver medal in the world ga-ga ball championships eventually coming in second to the undefeated Australian Habonim team.
All the usual Wikipedia disclaimers apply, of course, but how cool is that? Especially since being a ga-ga player over six feet tall is about as much a handicap as being a basketball player under 5’5″.
