Final Grunt

The Final Grunt, also referred to as the Jerk Store Grunt or Seinfeld Grunt, is a talking Grunt in Halo 3.

Description
This Grunt is found cowering on the edge of a cliff right before the player goes down the ramp to leap into the Forward Unto Dawn's hangar in the level Halo in Halo 3. As the player reach a white rock arch, turn the vehicle slowly to the right and a narrow pathway will be visible. At the end of the pathway is the Grunt. If the player approaches him, he will say:

However, discovering the Final Grunt may leave the player unable to complete the end of the level as the platforms would have broken apart, thus rendering no possible route available to reach the Forward Unto Dawn.

Trivia

 * The "Jerk Store" joke is possibly a reference to a joke on the American sitcom Seinfeld, in which George, one of the four main characters, tries to make a witty comeback at a fellow co-worker.
 * This Easter Egg has a striking relationship with the Thirsty Grunt which is located in the last level of Halo: Combat Evolved.
 * With the I Would Have Been Your Daddy Skull activated, players can hear normal Grunts say part of the quote on other levels, usually, The Ark or Sierra 117.
 * On single player, the Arbiter will fire the Chain-gun at the Final Grunt, preventing you from hearing the quote.
 * If the Final Grunt is killed while saying his dialogue, his dead body will carry on speaking. If he is knocked of the edge however, you will stop hearing him.
