It's probably no real surprise to fans on the show that John Becker comes from a broken family. He definitely has some social issues. So, the revelation that his father seemingly abandoned him and his mother when he's young isn't a shocker.
However, I greatly enjoyed Dick Van Dyke as Fred Becker. Ted Danson and he had great chemistry and Mr Van Dyke easily slid into the cast for the episode, playing charming and dapper salesman foil to Ted Danson's snarly and cranky doctor.
The ending is a bit bittersweet.. Dad is gone once again, but he's leaving a gift behind to say he regrets the lost time, the lost chances and leaves a hope of bridges to be further mended.
Overall, a great episode that makes many revealing insights into the character.
