As a collector, Shelley Jobe isn't goofing around. Except, she really is. In fact, she holds the Guinness World Record for the largest collection of memorabilia devoted to Walt Disney's Goofy. The middle-school art teacher invites Lisa into her home to see her dazzling range of items devoted to the beloved character - from a vintage lawn-mowing Goofy to a one-of-a-kind marionette, with plush pillows, squeaky toys and more in between. Lisa's brought along professional appraiser Josh Johnson, who will put a price on Shelley's entire collection - and then tempt her to trade for a vintage treasure from his own personal Disney collection. Also, Shelley gets a surprise message - and a special gift - from Bill Farmer, the longtime voice of Goofy in Disney animation.
