Background Blues

Summary
A class project gets the kids tracing their family trees. Will they turn out to be descended from royalty—or just from "plain folks"?

Plot
R4 was playing at the hologram with his robotic dog Hal when her sister 3W came and destroyed his hologram. His mom told him to do some homework. Later, he does his homework, then 3W shows up and asks R4 to play with him, which he agrees to. They were still fighting while playing, so their mom asks them to watch a datagram.

After the title card, Mr. Ratburn teaches the students about his family. Later at art class, Muffy and Francine begin to fight about their ancestors, but Arthur and Buster stopped them. Later at Buster's condo, he discovers he has more family. The next day while Arthur and Buster were looking at their family history, Muffy tries to find the Crosswire section, but to no avail. Then Francine showed up and told Muffy her grandfather owned a castle. Muffy then told her the Crosswires are too important to be in the library. At Muffy's mansion, Muffy's father suggests she visit her aunt. The next day, Arthur, Francine, and Buster were chatting about their report when Muffy showed up. Francine told her that her great-great grandfather was an advisor of Abraham Lincoln. Muffy then tells her she's going to see her great aunt. She then thinks if her great aunt's a queen, then she's her princess. Later, she arrives at her great aunt's house, and she gave Muffy a lawn gnome for her report. Meanwhile, Francine's grandpa gives her a picture for her report. Later at the Sugar Bowl, Francine and Muffy were fighting which led Muffy to admit her family were just plain people. That night, Francine was thinking about what to do when her grandpa showed up and encouraged her. The next day, Francine was about to give her report when her grandpa came in and told her she forgot her album. The report was great, then Buster showed his 1955 sandwich, which grosses everyone out.

Back in the future, R4 and 3W were talking about the video, ending the episode.
