November 8, 1999
While stuck in the attic crawlspace, Doug tries to pass the time by playing a game with Carrie - humming TV theme songs. Carrie guesses that he is humming the theme to 'Sanford and Son' but Doug tells her that it's supposed to be 'What's Happening!!'. When Carrie asks him how the theme to 'Sanford and Son' goes, Doug hums it for her.
