Comic actor Bob Dishyappears in this episode as a pharmacist who has made it his mission in life to protest against artificial food additives. The pharmacist takes his crusade to Mel's diner--where he announces his intention to dramatize his stand by committing suicide! The curious changes in the décor of Mel's Diner which are unique to this episode suggest that it was taped very early in Season Two, but held back for several months. ~ Hal Erickson, All Movie Guide
