Discussed: "Dammit, Bob... what do you want me to offer you? Cash? Booze? Sexual favours?" "I dunno... perhaps some apple pie would be good, mm-hmm?"
Conversed: "That Bob! He'll do anything for Alice. Or rather, he'll do anything for Alice's pies." "I know, right? She must bake the best pie in the universe!"
Played For Laughs:
Bob's reward for losing weight is half a ton of greasy potato chips.
Bob is an Extreme Omnivore, and Alice bribes him with non-food items which he eats.
Played For Drama: Bob is literally starving, and ready to do anything for food... which Alice ruthlessly exploits.
Untwisted: Bob says he won't work no matter what Alice may bribe him with. She offers him money, DVDs, and various other bribes, all of which he turns down. But when she offers him an apple pie in exchange for some chore, he accepts.
