Destroy the Core

The Events
One day, Matt was in Mike's basement playing video games. He had with him an audience of Shane and Mike. They watched with growing amusement as Matt struggled to beat a very difficult boss: Krauser of Resident Evil 4 on Professional difficulty (if I recall correctly), a very difficult feat, truth be told.

(unless of course you use the combat knife)

Probably due to watching him play through a Gradius game, Shane came up with a technique for beating the boss.

Shane: "Matt, you should just destroy the core."

Matt: "Shut up."

Mike: "Yeah, just destroy the core and you'll win!"

Matt: "Shut up!" *dies again*

Shane: "It's very simple Matt.  Just destroy the core!"

Matt: *growing more and more frustrated* "Shut the fuck up!!"

Matt died several more times, seeming unable to beat the boss even with the encouragement and good advice coming from his friends.

He had just received yet another Game Over when Shane decided it was time to leave. As Shane walked up the stairs, he commented over his shoulder that "Well, you might have won if you'd just destroyed the core, Matt."

An object flew through the air... Shane stumbled as he was hit in the ass by Matt's heavy wallet full of loose change, and the Shoob turned back to the screen, sulking apopleptically.

From that moment on, it's very easy to make Matt very angry when he's playing a frustrating video game. All you have to do is politely tell him what needs to be done !

Legacy

 * Anytime Matt is having troubles with a boss, his friends tell him to destroy that core.
 * A WoW Guild was created and named Core-Destroyers, just for him
 * The GURPS Space Game involved a space battle with a mega-ship with many weapons and a series of wafers protecting an energy core.  He very nearly rage-quit and left the party without a ship's engineer.
