This external shot of the sign at Mel's Diner is probably memorable to you if you watched the show...
Was this sign really made just for the show's theme song?
Actually, it wasn't. This is a real sign producers found at a roadside Phoenix establishment called "Chris' Diner", and they liked it so much that they asked the owner if they could use it for the show. The owner did them one better. He changed the name to Mel's Diner, and allowed the show to alter his sign to their liking. If you'd like to visit, it still exists:
It's off I-10 on Grand Avenue, and actually has good reviews. The cook won't tell you to "stow it", though, nor will any of the waitresses tell you to kiss their grits.
The Mel's Diner depicted in the show is supposed to be more on the outskirts of Phoenix, implied to be fairly close to Mesa on the east side of town.
All but two of the show's main cast has died. Tayback died at age 60 way back in 1990. He had a fatal heart attack, and his death was unexpected. The next cast member to perish was Beth Howland at the end of 2015. She was 73, and shortly before her death from cancer, she requested that her death be kept a secret for several months. It is not clear why she wanted this, but the promise was kept, and the public was not made aware of her death until late May 2016.
The biggest surprise was Philip McKeon's death in 2019. He was only 55, and the details of his death were very murky. Family reported that he had been "suffering from a long illness". There has been a lot of speculation around Hollywood regarding what really happened to McKeon. One rumor was that the "long illness" was actually AIDS. McKeon had been dogged by gay rumors throughout his career. It didn't help that he never married, never had children, and was never publicly linked to a romantic relationship with any females. Maybe if scenes like this were witnessed in real life, he would not have dealt with such rumors!
While lots of lifesaving therapies existed for AIDS in the 2010s, it is possible McKeon had it for a long time, and it wore down his body. There are other rumors that McKeon's "long illness" was depression, and he committed suicide. This is possible, but I do not have any evidence to support it. Others have said that McKeon's illness might have been some form of addiction. I have to imagine that the cause of death was hidden for a reason. Were it something like cancer, I'm sure we would have heard about it more specifically.
Interestingly, Phil was not the only McKeon to suffer through gay rumors. His sister, Nancy, best known as Jo from
The Facts of Life has long been assumed to be a lesbian. This mainly stemmed from the tough, tomboyish character she played.
Family Guy even did a gag which implied Jo was intersex...
However, Nancy has been married to a man since 2003. She is not likely to be gay.
Diane Ladd and Polly Holliday are still alive.
