Ironically, Jean Stapleton actually did do some various laundry detergent commercials previously before the All In The Family series.
Ironically guest stars Frank Aletter (Mr. Prescott) and Darryl Hickman (Peter Grey) portrayed boyfriends of Carol Traynor on the spin-off Maude in separate episodes.
Perky Potty Man is a parody of Ty-D-Bowl Man featured in a series of commercials as Edith describes.
Alan Hamel, who plays a laundry soap pitchman, was in fact a pitchman in real life. He was the spokesman for a chain of grocery stores. He had married Suzanne Somers two months before the airing of this episode and unusually (for a show-biz couple) they remained married until Suzanne's death.
