Trivia

 * He was Bob's best man.
 * He is most likely in his sixties. People generally start school at five and his wedding takes place about a year after Amelia Bedelia's First Day of School. Amelia is now about 26 so it's about twenty years later. If he has an adult daughter, he was probably in his forties then (if he had her in his twenties), so he's probably in his sixties now, however, he could be a bit older.
