'Late Night' will go all-skeleton for one night

Conan O'Brien has done an all-claymation show, shot a show opening during a blackout and taken viewers to Finland. On Halloween, the "Late Night" host will break more television ground.

In keeping with the spirit of the spooky holiday, the Tuesday, Oct. 31 edition of the show will be an all-skeleton version. As O'Brien says, "This may be the finest hour of television NBC has ever produced ... with skeletons."

The flesh-free episode is a re-creation of a "Late Night" broadcast from May. Conan's skeleton's guests will be the bones of Larry King (suspenders included), the skeleton of "House" star Omar Epps and the frame of actress Sheila Kelley ("Singles," "Matchstick Men"), who will demonstrate a pole-dancing workout that's become popular in L.A.

The show also features "Arrested Development" star Will Arnett's skeleton doing an "In the Year 2000" segment.

The skeleton episode will mark the second time "Late Night" has recast an episode. In May 2003, the show did an episode in clay animation (of which O'Brien similarly said, "This may be the best show we've ever done -- in clay"). "Late Night" has also broadcast from a Circle Line boat in the waters around Manhattan and shot the opening of a show using only reserve power when New York was under a blackout in 2003.

Perhaps most famously, O'Brien traveled to Finland earlier this year and filed a travelogue from the country, where he met with his doppelganger, President Tarja Halonen.
