Abraham Lincoln's head

Abraham Lincoln was a U.S. president in the late 19th century, famous for being the president directly or indirectly responsible for the abolishment of slavery in the U.S.

By the 31st century, he has become a head in a jar and despite his history, he doesn't mind advertising for car dealerships together with George Washington's head.

Production
Every time Lincoln or a version of him appear on screen, Matt Groening asks what it is with boys and Lincoln, specifically referring to Ken Keeler and David X. Cohen.
