Steal this idea - "The Way to His Heart"

Certain bacterias in your stomach make you crave certain foods, like chocolate. What if...

a). Comedy. Her biological clock ticking away, a woman scientist decides to inject the men of her dreams with a bacteria that make them covet the one great food she makes in the hopes that will spur them to love her, only to find out that the grocery delivery guy with a bad accent is really the hunk of her life and is an immigrant scientist from Tysklansksten.

b). Sci-fi. Friendly aliens decide to take over the Earth by getting the entire population addicted to an alien dish that we can no longer resist, but Muslim extremist refuse to eat the unholy dish. Can they save the Earth?

c). Horror. An addictive food turns most of the Earth's population into zombies. (Don't they always turn into zombies craving brains walking deadly slow but always able to catch up to an Olympic sprinter who trips over a moon beam to become their next meal?) Well, maybe not zombies, but a population consumed by only one goal: the acquisition of that food. How do we save ourselves? Think of the rotting mess.
