Ok, I searched long and hard to find a quote that can't be directly linked to the movie by that (welcome) spawn of Satan, Google. This is pretty obscure, so unless you've seen the movie, you may not get it.
[ Character one, offering up a snack: "Pork rind?" Character 2, nodding understandably: "Pork rind." ]
Reality: Oh, yeah! Pretty obscure. Clues available upon request.
