IMDB is pretty thin on uncredited actors/actresses where TV programs are concerned. This was almost certainly an uncredited “role.”
I’m not trying to challenge your memory or hearing. I see now it was a character named “Phil Hartman.”
Was the pharmacist shown in the episode? If the name was only mentioned in passing, then he wouldn’t be listed as a character on IMDB (because nobody played him). “Maris Crane” isn’t listed on IMDB either.
Yeah, I’ve been wondering that myself. It’s been a couple of years since I saw that one. I’ll have to watch it this afternoon.
Sidney Sheldon, the very prolific author of a whole crapload of books, created I Dream of Jeanie.
Chairman Kaga from the original Iron Chef once played Jesus in a Tokyo production of Jesus Christ Superstar .
“And the secret ingredient is…MY BODY!!!” 
Before starring on “ER”, George Clooney starred on a 1984 TV show. The name of that show was “E/R”.
Before becoming one of the stars of “The Matrix”, Carrie-Anne Moss was on a TV show that ran for 13 episodes in 1993, called… “Matrix”.
He also won an Oscar for writing the screenplay to “The Bachelor and the Bobby-Soxer”.
While it’s not movie/TV, the murder victim in the first Superman story was named Jack Kennedy
Only as a body, if that (i.e. no flashbacks to when he was alive). I don’t remember if the director made use of camera angles or a sheet to cover him up.
Listen closely. He says VTR (Video Tape Recorder), not VCR, which dates it even more.
There are tons of trivia points for my favorite movie of last year, There Will Be Blood. A few of my favorites:
“Paul Thomas Anderson stated that he watched The Treasure of the Sierra Madre (1948) every night before filming this movie.” (I love it because The Treasure of the Sierra Madre is one of my all-time favorite films)
“While on location in Marfa, Texas, No Country for Old Men (2007) was the neighboring film production. One day, director Paul Thomas Anderson and his crew tested the pyrotechnical effects of the oil derrick fire, causing an enormous billowing of smoke, intruding the shot that Joel Coen and Ethan Coen were shooting. This caused them to put off filming until the next day when the smoke dissipated from view. Both this film and No Country for Old Men (2007) would eventually become the leading contenders at the Academy Awards a year and a half later.” (I love it because if TWBB wasn’t going to win the big prizes, thank god they went to NCFOM and the Coens, and I love that they were filmed simultaneously)
“Daniel Day-Lewis accepted the role of Daniel Plainview as he had been a fan of Paul Thomas Anderson’s previous film, Punch-Drunk Love (2002). According to Producer JoAnne Sellar, the film might not even have been made at all if Day-Lewis declined the role.” (I love it because Punch-Drunk Love was my favorite film of 2002)
The writer of the Star Trek episode “The Trouble with Tribbles” was still in college when the episode was written, and eventually grew up to write the Hugo and Nebula award winning “The Martian Child.”
In the Phil Hartman Quantum Leap episode, the part of the cripple boy was played by Joseph Gordon-Levitt. He later gained fame on 3rd Rock from the Sun, which had a season cliffhanger that starred, in his last role…Phil Hartman.
That is beyond trivia and coincidence, and slipping into Twilight Zone territory.
