OK, this is probably a stupid and annoying question but what did it mean when Hodgins said something about a cat? I recognized it, meaning I've heard the term before, but I don't remember what it means. Schroedinger's (sp?) cat or something along those lines.
As far as the episode goes, awesome. I just hate that we aren't gonna see Zack anymore. I like him. I like his totally literal way of taking things, kind of how Bones is.
