To me, this is what Roseanne, the show, did best.
Two of my other favorite (similar) moments:
1. Jackie's phone call to the aunt about her father's death. "Dad's Dead!" This one is shown a lot, but it is a classic example of why Metcalf has all the Emmys and was so beloved.
2. The end of the episode where DJ wouldn't kiss the black girl. Roseanne and Jackie are at The Lunch Box, and a Big Black Man comes to the door. Roseanne acts as if they are closing, but eventually lets him in. The man turns out to be the little girl's father, and wants to discuss DJ and his little girl. After he leaves, Roseanne actually locks the door, pulls down the shade and says to Jackie, "We're not racist; are we?" Roll credits. So simple; so powerful, and yet left the audience to "figure it out."
