Every once in a while Nathan informs us of, well, some information that's, well, information, but it's just not useful info. But sometimes it's interesting. Last night he was giving us some tid-bits of info (which he likes to refer to as "knowledge") and this was one of the tid-bits. In short, he said that sleeping with the light on is not good for a person, because it makes it easier for that person to gain weight.
Zach pipes up and says, "Well, you might gain weight, but at least it'll be light weight!" And that, of course had everyone exploding with laughter.
