Caruso grew up in Eastbridge, where the local children knew never to go near Bartimous Hagstone's home because there were rumors he was a warlock.
Ricky Caruso (after finding the altar): What a way to spend a weeknight. Dinner, TV, a little human sacrifice ...
John Hibbs: Just because the guy lives in a pig sty does not mean he's a warlock. I mean, if that's the case, my whole family would be witches.
A hagstone, also called an adder stone, is a type of stone that has a naturally occurring hole in the center. The stones, often glassy or quartz-like are said to have magical powers and were part of many Druidic rituals.
Special billing was given to Ray Walston (Special Guest Star) in this episode.
Tony Scali: Didn't you guys ever watch The Honeymooners?
The Honeymooners, starring Jackie Gleason as Ralph Kramden, Audrey Meadows as his wife, Alice, and Art Carney and Joyce Randolph as neighbors Ed and Trixie Norton, ran on CBS from 1955-1956. This classic comedy sitcom is listed as one of TIME magazine's 100 best TV series of all time.
Bartimous Hagstone: Please call me Bart. As in Starr or Simpson. Bartimous? I don't know what my parents were thinking.
Bart Simpson is, of course, a well-known character from the TV show The Simpsons. Bart Starr played for the Green Bay Packers from 1956 to 1971, was the NFL MVP in 1966, and led his team to win the first two Super Bowls in 1967 and 1968.
Cyd Madison: Tony! I might have a lead on a motive for the case of the tell-tale heart.
"The Tell-Tale Heart" is a short story written by Edgar Allan Poe in 1843.
Jeff Hartley: But there is an ancient cult ceremony in Wales, an offering to Cerridwen, Celtic goddess of youth rejuvenation, made on Halloween.
According to Welsh mythology, Cerridwen is the goddess of the moon, femininity, harvest, nature, inspiration, and rebirth. She lived on an island in Lake Tegid (named after her husband) with her beautiful daughter, Creidwy, and a very ugly son, Afagdu. She was also believed to be the mother of the great Welsh poet, Taliesin.
Tony Scali: Present fears are less than horrible imaginings. Right, Mr. Harker?
Mr. Harker: What's that from?
Tony Scali: Macbeth?
Mr. Harker: Sure, if you say so.
Tony is correct; the quotation is from Act I, Scene 3 of Macbeth, spoken by Macbeth in an aside during his conversation with Banquo.
