Getting to watch Zombieland by yourself. And when I say by yourself, I mean your friends didn't come with you because they wanted to see Avatar instead; but it also means that you are the only person in the entire movie theater. You walk in and the room is empty and the projectionist puts his head in and waves and starts the camera up just for you. It's not platinum class seating, but hey, this is pretty nice.
You have the place to yourself, you laugh out loud and talked back to the screen. You could make some phone calls just to top things off, but there doesn't seem any point.
