* Veronica drags Billy out by the ear and gives him [[WhatTheHellHero a good ass-chewing for mocking a fellow third-grader's stutter]]. It's even better in retrospect to see her call him out on his bullying so sternly, considering how many of Sandler's later movies have been criticized for picking on what they deem AcceptableTargets.
* [[http://www.youtube.com/watch?v=5hfYJsQAhl0 Billy Madison's principal's response to his wrong answer at the Academic Decathalon]].
* Billy's thoughts on "The Puppy Who Lost His Way":
--> ''"...That little boy's gotta think 'You got a pet! [[SeriousBusiness You got a responsibility]]!' If your dog gets lost, you don't look for an hour then call it quits. You get your ass out there and you '''[[PrecisionFStrike find that fucking dog]]!'''"''
* While Billy isn't well-schooled or anywhere near a genius, he seems pretty capable with understanding people. For example, knowing that getting [[ScrewTheRulesIHaveMoney Eric]] to answer a Business Ethics question during the Decathalon would force his rival to [[VillainousBreakdown 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''.
-->'''Billy:''' ''Man,'' I'm glad I called that guy.
* Billy's classmates demanding the principal to recant his false confession.
