In the episode in which Woody from "Cheers" visits Fraser, there is a slip-up. They are in Fraser's apartment and Fraser is showing Woody a "picture" from a Seattle guide book. However, when Fraser then turns to show Woody the great view, if you look at the book, it looks like there is only text on the page with the "picture". I might just be picky, but I think the producer could at least find a book with a picture!!!
