Marge and the Butt-scratcher

While house-sitting for Mr. Burns, the family sits down to have sloppy-joes for dinner, and they end up using a bunch of different pieces of silverware—Marge notes that it's probably overly elaborate for something as simple as sloppy-joes and admits that she knows what all but one of the forks are for. The only fork that Marge doesn't know is very long, but according to Homer, it's apparently a good butt-scratcher.
