History
After Homer gets much better at teaching as professor in Burns University, Mr. Burns decides to sell him to Bourbon Verlander and let him work for him at his private estate. When Homer arrives, he meets one of the educators that Verlander hired for him, Neil deGrasse Tyson, an astrophysicist. He tells Homer the fact that the solar system is over four and a half billion years old. Homer also meets Robert McKee, Suze Orman and Ken Jennings, the other educators that Verlander hired. He is later seen teaching Lisa Simpson astrophysics and showed her the rings of Saturn through a telescope.

When Benjamin asked Doug and Gary who is the most average person they know, Gary said that it's Neil deGrasse Tyson, while Doug said that it's Michio Kaku. Benjamin then told that perhaps they should set their sights a little bit lower.
