Schroeder: This is the music I've selected for the Christmas play. Lucy: What kind of Christmas music is that? Schroeder: Beethoven Christmas music. Lucy: What has Beethoven got to do with Christmas? Everyone talks about how great Beethoven was. Beethoven wasn't so great. Schroeder: What do you mean, Beethoven wasn't so great? Lucy: He never got his picture on bubblegum cards, did he. Have you ever seen his picture on a bubblegum card? How can you say someone's great who's never had his picture on bubblegum cards? Schroeder: Good grief.
Schroeder plays Beethoven as his selection for the music for the Christmas play. They argue about his choice with Lucy explaining that no one can be great if they are not on bubble gum cards. They are in the auditorium and Schroeder is on his piano, and Lucy is leaning on it.
