The guy had studied animal husbandry and he told my co-workers and me that if you inserted a foreign object (about the size of a quarter) up into the reproductive area of a hen at _just the right time_, the hen would often lay an egg with the foreign object trapped inside.[1]
Our business plan:
* get a bunch of hens
* have guys mail $500 + engagement rings to us.
* insert engagement ring into hen
* ship back ring-encased egg to the dudes.
* dudes ask girlfriends to cook an omelette...
I still wonder how anyone figured that out.
