Sen. Al Franken, who got his start in television on Saturday Night Live, returns to the little screen today for an appearance on the game show "Jeopardy." Franken will match his knowledge of minutiae with other contestants to make money for the USO, which helps U.S. military members and their families. If Franken wins, the USO gets $50,000. If he loses, the group still gets $10,000. The show airs at 3:30 Central Time on NBC.
