Trying to catch a greased pig is an American tradition that has fallen out of fashion — so you're forgiven if you don't know the rules.
The game, once a staple of county and state fairs, is simple enough: A small pig is covered in lubricant and thrown into a ring where contestants try to catch the animal. What makes it hard — and fun to watch for spectators — is that pigs are shiftier than lumbering humans. Just when you think you have a grip on them, the slick porker can slip through your fingers. And when it's all over, both pig and human end up dirty.
