Person 2: "Wow, sounds like you've got a case of Shopper's Amnesia."
2. Lisa went to the store and found the hit Drew Barrymore film Ever After in the bargain bin for only $9.89. Lisa loves Drew Barrymore. Upon arriving home she attempted to put the new DVD into her alphabetically categorised collection, only to discover that she already owned a special edition copy of said film. Lisa blamed this unnecessary purchase on momentary Shopper's Amnesia.
