I tuned in to American Idol last night, waiting on bated breath to hear whether Danny Gokey or Kris Allen (Adam Lambert was a shoo-in) would be moving on to next week's finals. But instead of squeaky clean Ryan Seacrest, Ben Stiller was the first to grace the screen. Soon joined by fellow Night at the Museum: Battle of the Smithsonian actors Hank Azaria, Bill Hader (of SNL) and Jonah Hill (of Superbad), Stiller announced that the American Idol judges' desk is on its way to the Smithsonian. (It will go on view later this summer at the Smithsonian Castle Building, sometime after next week's finale.) Of course, the stars couldn't pass up the opportunity to poke fun at easy targets Simon, Paula, Randy and Kara.
