It must be heard to truly appreciate the awesomeness.
It shows up again in Gears 3. If you activate the Thrashies ad that plays sound repeatedly, it will eventually play the rant instead of it's usual soundbite ("The Cole Train runs on whole grain, baby! Whoo!").
As the Lambent board the Sovereign in Gears 3, several drones go through Dom's garden (and if you gun them down, they explode in Dom's garden).
When Cole returns to Cougars Stadium, his old home field, the Lambent follow and a fight breaks out on the field. He goes into an Indulgent Fantasy Segue where he's running a bomb like a football past waves of Lambent and "spikes" it on the Stalk. While he's doing an endzone dance, the stalk explodes, sending him flying. The others come over to him and try to move him, only for him to pop up like nothing happened.
Cole: Haha! The Train's still got the moves, baby! Now that was a move I first used against the Eagles in the national finals! Course, them bitches didn't explode!
Even better: The explosion literally knocks Cole out of the flashback! Before it goes off, he (thinks he)'s wearing his thrasball uniform, and after he lands, he's back in his real armor.
Cole: "Uh, puttin' it scientifically? We need to blow his brains out his ass!"
When part of Delta is about to fall off a collapsing bridge in Gears of War 3, we get this gem from the ever sarcastic Damon to Samantha Byrne:
Damon: "I suppose you want me to say I've always loved you. But I don't! I really, really don't!"
While exploring the Savage Locust fortress:
Dom: So, any idea where we are now?
Damon: Um... in the shit. (holds hand over his head) Up to here.
"When a Mommy Corpser and a Daddy Corpser love each other very much..." It's just the way Damon delivers that line that sells it as one of the funniest moments in the entire game.
The hilariously awkward scene in the elevator near the end of Gears 3, culminating in Marcus yelling for someone to shut up the intercom and Baird obliging by swiftly shooting it with his Snub before immediately going back to the conversation.
An Easter Egg in Gears of War 3 has you fight a giant, golden, fire-breathing chicken that explodes into rainbows when you defeat it.
The video at the 2010 Comic-Con, calling for fans to vote whether Clayton Carmine lives or dies. It has Dietrich Carmine applying for life insurance, only to be declined as the family is bankrupting the company. The various ways the salesman describes how Carmines die is especially hilarious.
Watching Marcus charge a Locust soldier with his chinsaw roaring only to whip around and destroy a couch because the color deeply offends him is hilarious.
"Eat shit and die!" is a one-liner that several of the COG say in multiplayer. Griffin, however, puts his own spin on it by saying "Eat shit! And then eat more shit!"
