This is the first appearance of many for Brandon Douglas on the show but the only appearance of his character, Randolph Cummings. He returns later in the same season (and future seasons) as Dr. Andrew Cook.
When Loren, Jake, and Hank are sitting in front of the store discussing their upcoming fortunes, Hank asks if Jake's "going to branch out into cutting pet hair, like that little Fifi rat dog?" This refers to the previous episode Fifi's First Christmas (1995) when Brian received a miniature poodle from Dr. Mike's mother in Boston in lieu of his lost dog, Pup.
Eugene O'Neill wrote The Iceman Cometh in 1939.
The Iceman Cometh is a play.
Fifi was a Bichon Frise, not a poodle.
