I initially had just the pig versus Patrick, but it was pretty clear that the pig would win, so I made it more interesting by giving Patrick a knife. I still think the pig would win. Patrick would end up stabbing himself somehow.
Patrick would never win. He can only win at stupidity. However, I have a hard time thinking of this generic pig doing anything. Because it's a generic pig, I can only think of this as a keychain. Am I supposed to imagine this pig keychain doing something? On the other hand, Patrick has a personality from the tv series. I can imagine Patrick doing stuff.
