The Decapitation of Larry Leadfoot

The Decapitation of Larry Leadfoot is an educational film starring Troy McClure.

History
After Homer got a ticket for drunk driving, he was ordered to attend traffic school. Chief Wiggum showed an educational/safety film starring Troy McClure, where Troy said to the viewers, "You might remember me from such driver's ed films as Alice's Adventures Through the Windshield Glass and The Decapitation of Larry Leadfoot."

Behind the Laughter
The film's title is a reference to the former practice of showing driver's education students films of gory accident scenes in order to graphically illustrate the consequences of unsafe driving.
