- Elf Dwarf

History
In Burns' Heir, Bart is driving his new sports car when he hits the Elf Dwarf. He survives the collision, landing into the back seat of the car.

Estonian?
Later in the episode, actors play the roles of the Simpson family in attempt to trick Bart. One of the actors is an Estonian Dwarf. The two characters resemble each other almost identically. So it is possible that they are the same person, or that they are related.
