In the DVD version of this episode Chris Farley has a small role in the scene where Roseanne, Jackie, and Nancy are shopping.
The title comes from a play on words from the screenplay 'Glengarry Glen Ross' by David Mamet. It won the Pulitzer Prize in 1984. The title comes from two real estate developments mentioned in the play. 'Glengarry Highlands' is the prime real estate everyone is attempting to sell now; 'Glen Ross Farms' is mentioned by several characters as having been very lucrative for those selling it several years before.
