Mount Rushmore is a famous stone sculpture from the Black Hills, South Dakota region of the United States on Earth. Its initial form featured massive sculptures of the heads of George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln.
In the 2600s, when New Yorkers elected a super villain governor, Mount Rushmore was stolen and installed on Monument Beach, and the likeness of the governor was then added next to Lincoln. This confused Fry, as he didn't know that both it and the Leaning Tower of Pisa were in New York. The sculpture was subsequently destroyed by the Omicronian's Monument Destroying Laser in 3000.
