The majority of Gordon's lines are hilarious. An example: "This looks like a sheep's turd that's been infested with ants."
In the "Michon's" episode, Gordon is ripping into the kitchen staff, and demands to know if there was anything in his lunch that wasn't heated in the microwave. After a slight pause, one chef chimes in with "The salad."
When Gordon leaves the room to try to clear his thoughts after talking to Sebastian, the cook is convinced that he has outwitted Gordon and goes around the kitchen announcing, "I think I just won that one!"
When Gordon returns to Lanterna, the sous chef Aldona screams, and when the head chef asks her why she tells Gordon, "I had a dream about you last night. You killed me."
If you're into schadenfreude, the episode "La Para de Burianna" has the opening night after Gordon gives them their "idiot proof menu", where Gordon more or less has it as a safety net for the head chef Lawrence to fall back on when his menu and serving style inevitably fails. However, it does not just fail, it fails hard. Lawrence begins serving bad food as usual, gets into an argument with barbeque chef Norm who can't even find his basic materials and the manager, Alex ends up getting so screwed up regarding who is being served what that he ends up serving food to tables nobody is even sitting at. They don't use the new, easier-to-cook menu for well over an hour. The whole while, a band plays a happy Spanish party tune, with Gordon standing in the background with his hand on his face.
The entirety of the Amy's Baking Company episode, in a Bile Fascination way, starting with Gordon's increasing bafflement over Amy's obsession with internet bloggers.
Especially at the beginning, when one couple says that their salad doesn't taste right. Sammy's response is that they don't have any idea what is wrong with it:
Sammy: If you came here to eat, to enjoy, then you should know what you like to eat, sir!
Female diner: Apparently you don't know what you like to eat.
Male diner: I guess not!
At one point Gordon confronts Amy over firing a worker for asking a question. She asks him if he'd let anyone speak to him like that in his kitchen, and he responds with a casual "yeah".
Gordon trying to find a way to wrap his mouth around the Burger Kitchen's one-pound Cowboy Burger.
Martin, the Camp Gay manager of Santa La Brea, flawlessly mimicking Gordon's accent as well as his signature "get-your-fucking-shit-together" triple-backhanded-palm-slap.
From the "Sebastian's" episode: "You guys are about to become great tossers". Of course, we're talking about tossing pizzas, but watching with the other meaning (British slang equivalent to "wanker") in mind it's hilarious. Hard to believe Gordon wasn't venting a bit and using it as a excuse to call some people tossers.
At Cafe Tavolini, one of the waiters was scared that Ramsay would stab him with a fork if he disagreed about the quality of the food.
Also from the Curry Lounge, Gordon takes the restaurant staff out to play a game of cricket as a team-building exercise, and he ties one of the owner's hands behind his back to show how his micromanagement has hindered the staff. Despite having only one hand, he manages to return the pitch and nails Gordon right in the ribs.
"Why are you throwing my lemons away?" "BECAUSE THEY'RE MOULDY YOU PILLOCK!"
From Spin-a-Yarn, Gordon having the waiters mime a funeral procession.
From Lido di Manhattan, Gordon trying and failing to convince the cameramen filming him to try a bite of awful tuna.
From Prohibition Grille, Gordon ends up locking himself in a freezer out of sheer embarrassment at Rishi's bellydancing.
