Episode Title:
Lemons!/The Butterfly Collection
Episode Description:
Lemons!: Carl starts a lemonade stand. When Carl asks Sheldon to help him run the stand, Sheldon reveals that he is afraid of lemons, having once sustained an eye injury from one. Carl tries to help Sheldon overcome his fear, eventually giving him a pair of goggles to protect his eyes while running the stand. While serving lemonade, Carl accidentally trips and douses Sheldon in lemonade. Unscathed, Sheldon stays at the stand as Carl makes a new batch of lemonade.
The Butterfly Collection: Carl prepares a bottle to keep his three black swallowtail butterflies after they complete their metamorphoses. He learns from a book that butterflies need nectar, which he cannot gather, and is angered when Sheldon expresses concern about the butterflies experiencing asphyxiation in the bottle. Maude asks Carl to consider how he would feel if he was trapped in a jar and to consider his choices regarding the butterflies. When the butterflies emerge from their chrysalis, Carl decides to hold a farewell party and set the butterflies free.
