Scooby Doo 2: Monster Unleashed (EUM)

Not everyday you get to see a zombie wearing tighty whities. In the second Scooby-Doo movie, real monsters wreak havoc around the city and the gang gets to fight them. At the end of the movie, it's up to Scooby to turn on a machine that will defeat the monsters, in the process, he takes care of the monsters one by one. 

This includes dashing between the legs of the zombie and ripping the back of his pants, revealing a pair of old worn out briefs. The monster covers himself in embarrassment. 

A great little moment that shows a cartoon character humiliating an enemy by exposing his uncool undies to the world.
