King Tut's real name, Professor William Omaha McElroy, is revealed in this episode.
King Tut's mundane name is stated as "William Omaha McElroy" as an homage to series producer William McElroy Dozier, who was born in Omaha, Nebraska.
Tut calls Batgirl "The Dynamic Duenna". A duenna is an older woman acting as a governess or chaperon in charge of girls.
This was Victor Buono's final appearance as Tut. However, the character did appear in the penultimate episode, but was portrayed by a different actor.
The name HL Hunter spoofed that of real life Billionaire/Industrialist HL Hunt.
