I always liked this Cosby Show episode in which Vanessa steals a sweater and gets a bad grade on a history test. And then, at the end of the show (around 5:30), for no real reason, Rudy is on the couch watching the famous Martin Luther King Jr. "I have a dream speech." The whole family gathers in silence to watch—it's a nice moment. And then Denise forgives Vanessa for stealing the purple sweater. Happy MLK Day.
