It might shock some Disney fans to learn that Goofy once had a wife. Considering that she's never mentioned in Goof Troop, her existence has become the stuff of legends — and fodder for endless rumors. Oddly, Mrs. Goof, also known as Mrs. Geef (depending on who you ask), doesn't have an official name or a clear and consistent physical appearance. What's even more surprising about this elusive character is that many fans believe Goofy's wife to be dead.
