Perhaps some of you recall last fall when Andy Richter pummeled Wolf Blitzer on celebrity Jeopardy. O.K., Andy is intelligent and educated so that's not necessarily a huge surprise. The latest celebrity Jeopardy pitted Anderson Cooper, Aisha Tyler, and Cheech Marin against each other. Before final jeopardy Cheech - yes Cheech - lead both Cooper and Tyler( who were tied with $8,000) with $14,200. The final Jeopardy question that stumped them? Basically, who wrote "The Wizard of Oz." Tough one. Cheech claimed not to get the answer because he read the date wrong (1980 instead of 1890). At least Cheech gave a reason. If you'd like, watch the final Jeopardy question - Cooper is visibly pleased to have his ass handed to him by none other than Cheech Marin.
