Billy Madison/Awesome

"Billy: Man, I'm glad I called that guy."
 * The wrong answer in the Academic Decathalon.
 * While Billy isn't well-schooled or anywhere near a genius, he seems pretty capable with understanding people. For example, knowing that getting Eric to answer a Business Ethics question during the Decathalon would force his rival to flame out.
 * Billy's former childhood victim, who he made amends with and befriended, appearing at the end to save Billy by shooting Eric. In the ass.
