I knew they'd end up there sooner or later. On Saturday, the Smithsonian Institution in Washington unveiled its latest exhibit: "Jim Henson's Fantastic World." The exhibit features 14 of Henson's Muppet creations, including Bert and Ernie, Kermit the Frog, and others from the long-running Sesame Street. The exhibit is scheduled to remain at the Smithsonian until October, then leaves on a three-year tour to seven other cities.
