At Schroeder's Glee Club, Patty is the only one to arrive early. When everyone comes, it's chaos. Unfortunately, a fight ensues between Lucy and Linus over a pencil. Lucy threatens to tell Patty that Linus called her an enigma. The fight spreads, and Charlie Brown decides to leave with his angry friends, leaving Schroeder and Snoopy the only ones singing ("Glee Club Rehearsal"). Later, Charlie Brown comes across Lucy teaching Linus about nature the way she views it, with "facts" such as bugs pulling the grass to make it grow or snow coming out of the ground in winter. Charlie Brown tries to correct her, but she retaliates with a false explanation, and Charlie Brown bangs his head against a tree in frustration ("Little Known Facts").
