Gypsies used a similar trick to get free lunch, they called it "nail soup". Tell the host that you can cook a "nail soup", a soup based on a nail.
Ingredients:
- One big nail
- Water
- Groats
- Bacon
- Salt, Spices, Herbs
- (...some more foodstuffs, I don't remember).

The idea was to cook a basic groats-based soup with nail in it. The nail didn't provide anything to the soup except of curiosity factor that made the host to provide the rest of the ingredients. The gypsy would eat one bowl, the host another, the nail would be saved for another cooking of the soup...

Here they use band-aid instead of the nail.
