Final Grunt

The Final Grunt (one of the Talking Grunts, often called the "Jerk Store Grunt") is found cowering on the edge of a cliff right before you go down the ramp to leap into Forward Unto Dawn's hangar in the level Halo in Halo 3. When you're at the top of the ramp leading to the Dawn's hangar, you should be under a rock arch. If you get out while under the arch and face Forward Unto Dawn, to your right is the Grunt. You should see him. If the player approaches him, he will say:

"Hey, Demon! The jerk store called, and THEY'RE ALL OUT OF YOU! Poor you, stolen at the age of six and conscripted into the military, waaaaaah! ...Okay look, if you let me live, I got the Fist of Rukt. Look, I'll be the bottom. I'll polish your boots. I'll polish your helmet! It's the gas, haha! When I'm on the gas, I don't know what I'm doing half the time!"

However, discovering the Final Grunt may leave the player unable to complete the end of the level and the game, because there will be no route available to reach the Forward Unto Dawn since the platforms may have broken if you aren't quick enough. Also note that if you drive up to the Grunt in a Warthog with the Arbiter at the gun, he will shoot and kill the Grunt before you can reach him. Make sure you keep the Grunt out of the Arbiter's line of sight, or the AI Arbiter will kill him.

Trivia

 * The Final Grunt, is also known as "The Jerk Store Grunt" or the "Seinfeld Grunt".
 * The "Jerk Store" joke is 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 fellow co-worker.
 * If you kill this Grunt, it will continue to make its speech. If the Arbiter kills it, it will not make its speech. If you kill it while its saying its speech, it will continue. In other words, as long as you come near the Grunt, it will say its speech.
 * This Easter Egg has a striking relationship with the last level of Halo: Combat Evolved. In the last level, The Maw, it is possible to find another talking Grunt that won't attack, the Thirsty Grunt.
 * "The gas" might actually refer to the methane gas that the Grunts breathe. However this would be unlikely, as they breathe it as we breathe oxygen. It is more likely he was running out/had run out of methane, and was breathing oxygen and feeling light-headed.
 * Another explanation could be "the gas", refers to a type of gas that the Brutes possibly added to the Grunts' methane, in order to increase their aggression, as is referenced by a Marine on the level Sierra 117.
 * A third explanation could be that "the gas" is benzene, referred to by Kwassass from Ghosts Of Onyx as "lovely lung gold".
 * With the IWHBYD skull is on, you can hear normal Grunts say this on other levels, usually The Covenant or The Ark after you kill another nearby grunt.
 * Even if only the Arbiter goes up to the Grunt, he/she will still call him Demon, even if the Chief is not there.
 * On the back wall of Valhalla, there is a shadow of a Grunt holding a large Gravity Hammer on the edge of a cliff. This may be a reference to the Jerk Store Grunt.
 * The Grunt is referring to when the Chief was taken from his home to join the UNSC when he says "stolen at the age of six and conscripted into the military"
 * On single player if you drive a little past the rocks the grunt is behind and stop the the Arbiter will shoot him.
