Homer: Do you sell toys?
Shopkeep: We sell forbidden objects from places men fear to tread. We also sell frozen yogurt, which I call frogurt. Homer: Well I need something for my son's birthday.
Shopkeep: Ah, perhaps this will please the gentleman (points to a talking Krusty the Clown doll). Take this object , but beware it carries a terrible curse.
Homer: Oh, that's bad.
Shopkeep: But it comes with a free frogurt.
Homer: That's good.
Shopkeep: The frogurt is also cursed.
Homer: That's bad.
Shopkeep: But you get your choice of topping.
Homer: That's good.
Shopkeep: The toppings contain potassium benzoate.
Homer: (blank stare)
Shopkeep: That's bad.
Homer: Can I go now?
