My favorite fast food is In-n-Out by FAR, but I'd have to say that my favorite is Wendy's and my wife's favorite is McDonalds. When I go to Wendy's I usually get a Big Bacon meal, no tomato. The wife gets Big Mac with no pickles, extra sauce.
If, by chance, we are in the part of the country with an In-n-Out, it's double-double with cheese and a shake. It doesn't really matter what you get at In-n-Out, because their menu is so small and it all tastes about the same: awesome. I guess what you order has more to do with HOW hungry you are, not WHAT you are hungry for - after all, you know you are hungry for In-n-Out, and once you get there, that's all that matters.
Harold and Kumar were dumbshits - they would have gone to In-n-Out if they knew about it.
