There's a story about feeding wild hogs that really rings hard with SOPA and other bills like it.
If you put out feed, hogs will come and eat. Once you get them hooked you drop one side of a fence. They'll be skiddish at first, but as long as you keep feeding them, they'll keep coming around. When they're back, they'll eat some more and you drop another part of the fence. Just keep it up until you have them used to coming around and feeding then drop the fourth and final part of the fence and you have them pinned in and controlled.
