From Muppet Wiki

Mount Rushmore is a national monument located in Keystone, South Dakota. A Muppet caricature appears in 1975's Muppet Show pilot, Sex and Violence telling jokes. They are played here by Jim Henson (George Washington), Jerry Nelson (Thomas Jefferson), Frank Oz (Teddy Roosevelt), and John Lovelady (Abraham Lincoln). The oblivious Washington frequently said "I don't get it."

They would appear twice more, rebuilt as different puppets. In the 1980s, they could be seen in a PSA for the National Wildlife Federation with Kermit the Frog (in his Sesame Street reporter's outfit). In 1996, they reappeared in Muppets Tonight episode 106. They laugh in Beavis-and-Butthead style, after having seen Gonzo zoom past them on a rocket.

A draft of The Muppet Movie script featured a scene where the heads of Mount Rushmore agree to let Henry Kissinger join them. Although this scene wasn't filmed, the real Mount Rushmore was seen in the movie, during a montage for Fozzie's rendition of "America."

Most recently, a computer animated version of Mount Rushmore co-starred with Miss Piggy in a Pizza Hut commercial in 2004.
