S1·E34 Ricky Thinks He Is Getting Bald

Ricky fears that he is going bald, so Lucy takes it into her head to help him: she stages a "bald people's party" to show him that he's not so bad, after all. But when that doesn't work, she resorts to showing some new "hair treatments" (or "torture tactics" as Lucy calls them) to show Ricky how silly he's been.
