: A character can only make one kind of food; if they try anything else they are a Lethal Chef
- Straight: The only thing Bob can cook is hard-boiled eggs.
- Exaggerated: Bob cannot even make soft-boiled eggs! Any attempts to diversify the menu end up with him setting the stove on fire.
- Downplayed: Bob can only make dishes that involve eggs; his repertoire ranges from omelettes to custards to French toast.
- Inverted: Bob is a Supreme Chef who can cook nearly everything under the sun except hard boiled eggs.
- Subverted: It's Bob's turn to make breakfast, and understandably, everyone expects that he'll make hard-boiled eggs. Instead, they wake up and see he has made some rather tasty looking pancakes.
- Double Subverted: The pancakes only look tasty! They really taste horrible!
- Parodied: Whenever Bob attempts to diversify his cooking, things end up blowing up, somebody get poisoned or worse...the food causes a zombie apocalypse!
- Zig Zagged: Sometimes, Bob can make other dishes perfectly. Sometimes, it turns out so horribly that he had to resort to hard-boiled eggs.
- Bob is a decent cook who can cook several dishes.
- Bob is an awful cook and can't even make one thing right.
- Bob has never made any attempt to cook anything.
- Enforced: ???
- Lampshaded: "Let me guess, Bob. I can have hard-boiled eggs, hard-boiled eggs, or... let me see... hard-boiled eggs! I mean, we all know it's the only thing you know how to cook!"
- Invoked: Everyone in Bob's life loves his hard-boiled eggs, so he never bothers to learn to cook anything else.
- Exploited: When the Big Bad captures and brainwashes Bob, he...
A) ... uses Bob to lull people into a false sense of security ("I heard that Bob's hard-boiled eggs are awesome! I just can't wait to see what else he can cook" from distant acquaintances).
B) ... uses Bob's other dishes as a Cool and Unusual Punishment.
- Defied: Bob learns to cook something else.
- Discussed: "Bob, I think you should learn to cook something else. I'm getting bored of these hard-boiled eggs."
- Conversed: "Why doesn't Bob cook anything but hard-boiled eggs? Is he a One Note Cook or what?"
- Implied: Bob always serves hard-boiled eggs, but this is never mentioned by any character.
- Played For Laughs:
- Played For Drama: Alice asks Bob to cook a meatloaf for a family dinner. Bob has never had to cook anything but hard-boiled eggs before, so despite his attempts to follow the recipe he was given, he sets the kitchen on fire. The fire burns Troperville to the ground, and every main character dies except Miriam, who was conveniently out of town. When she learns that all of her friends are dead, she suffers a severe case of Survivor Guilt.
