Murder, She Wrote
(CBS, 1984-'96)
We're informed by Marcia W., who messaged us on Facebook on May 9, 2018:
I am watching an old episode ("Incident in Lot 7") of Murder, She Wrote. A body has just been discovered in the Universal Studios' building that had been used as the Bates' house in the movie, Psycho. One of the characters described his regard for the dead man, "If I had to tell anyone that I liked the guy, I'd get struck by a bolt of lightning the size of Rhode Island."
"Incident in Lot 7," S8E13, aired January 19, 1992.
