Go to scene four on the DVD, or in the beginning of the movie when they are giving the introductions. Skip forward to the part where Zeke is in the bathroom giving out the fake IDs. When he decides to throw in his "special formula," he pulls out two pens both facing bottem end up. When they switch back to him, right before he says, "Guaranteed to jack you up," and before they show his name, the pen on the right is top end up while the pen on the left is Bottom end up. I noticed this the first time I saw the movie.
