Season 16, Episode 15 - "There's Noel Place Like Home"
Noel believes that everyone around him is either in love or getting married, and starts thinking about his own romantic future. Adding to his panic, Noel’s train breaks down on the way home and he winds up getting stranded with a group of very odd people. One cart contains several passengers who can’t keep their hands off each other, while the other is full of miserable older folk who seem to be sitting alone. Noel must decide which cart to sit in, and sees it as a life-altering decision. Before he can make the choice, the train starts moving again and Noel arrives home. The next day, Noel impulsively decides to leave Seattle to re-unite with Bonnie in Nevada. Bulldog and Gil throw a quick “bon voyage” party for Noel, but they forget to invite the guest of honor. It is revealed that Roz had wanted to fire Noel all these years because his job wasn’t actually important, but she never had the heart to go through with it.
