"Usually a pale creepy guy staring at you from across the dining area just means you're eating at Denny's."

This is a joke from the Rifftrax version of Twilight. If you don't know what Rifftrax (more famously known as Mystery Science Theater 3000) is, it's basically an audio commentary for a [usually bad] movie. The people doing the commentary spend the whole movie just making fun of everything going on on screen. If you're one of those people who really hates it when people talk during movies (even really bad ones), than this isn't for you; otherwise, you should definitely check this out.
