* SugarWiki/AwesomeMusic:
** The show's InstrumentalThemeTune, "Park Avenue Beat", by Fred Steiner. [[http://www.youtube.com/watch?v=paAIbMKb7eY Seriously, just listen.]]
** Equally awesome is the [[http://www.youtube.com/watch?v=aJqbBwLdfEE rerecording]] used for the TV movies.
* CantUnhearIt: Ever since the television series and {{Made for TV Movie}}s, it is impossible to read any of the novels without hearing Raymond Burr as the title character, or Barbara Hale as Della Street, or in fact most of the main cast.
* HilariousInHindsight:
** In one episode, Mason defends a man played by Robert Stack. Decades later, Raymond Burr hosted the first ''Series/UnsolvedMysteries'' special before Robert Stack took over the job.
** Some of Raymond Burr's previous roles as TheHeavy (or, in the case of ''Film/RearWindow'', the [[spoiler:murderer]]) could count as this thanks to Perry Mason eventually becoming Burr's best-known role. In fact, Burr had played the ''District'' Attorney in one film.
** The same also goes for William Talman, who played DA Hamilton Burger in the original series -- Talman got his first major role as a psychopathic serial killer in the 1953 FilmNoir ''The Hitch-Hiker''.
* HoYay: "The Case of the Jaded Joker": Comedian Danny Ross lives in a house with a man named Freddie Green, and they seem to spend a lot of time together. Danny is also adamant that Perry represent Freddie.
-->'''Paul Drake:''' One day, [Freddie]'s picking up pennies, doing two-bit errands for any guy that's got two bits in his pocket. The next day, he's living in luxury at Ross's expense.
** Female example: In "The Case of the Gilded Lily", Mrs. Brent and the secretary, Enid Griffin seem to take more of a liking to one another than one would expect for mere acquaintances.
*** In "The Case of the Foot-Loose Doll", [[spoiler:the false]] Fern Driscoll seems to have a kind of thing for the just-dumped fiancée, Mildred.
** "The Case of the Deadly Double" (a standard SplitPersonality plot[[note]]of course, they refer to it as "classic schizophrenia"[[/note]]) has Paul and Perry investigating the apartment of gentle Helen's feisty other self, Joyce. They find Helen's ex-husband dead on the floor, and are examining Joyce's purse when Tragg walks in, and the following exchange ensues:
--> '''Perry'''. Well, come in, Lt. Tragg. We were just about to phone you.
--> '''Lt. Tragg'''. I bet. I'm surprised, Mason. A fashion plate like you in the company of anyone improperly attired. ''(Paul is still holding Joyce's black purse)''
--> '''Perry'''. Yeah, I see what you mean, black bag, brown jacket. Well, some people just have no taste.
--> '''Tragg'''. Exactly. No private detective would be carrying an evening bag when dressed for the afternoon. Not even an ex private detective.
--> '''Paul'''. ''(looks guilty as hell)'' Now wait just a minute. Perry can explain everything.
--> '''Tragg'''. Yes, I'm sure he can.[[note]]Raymond Burr was gay, and this may or may not have been an intentional gag, although he was extremely closeted.[[/note]]

** Upon re-watching the series (Ho-yay in hindsight?) there were multiple Tragg/Perry Interactions that implied that the they were far 'closer' than simple members of the legal profession.... It has now become my head-Canon that they were a couple. It takes minimal effort to re-see Perry/Della more as Will & Grace than Sam & Diane... that the series Proper ended in 1966, the reunion Movies started in 1986 and they never expressly 'hooked up' just feeds into this... a side theory to this that Paul Jr. is Della/Paul's child (Katt's age hinders this, but since there was little if any mention of Paul Sr. having a Family in the series, it's an issue to canon time line as well)

* OnlyTheCreatorDoesItRight: Some fans apply this to any revival done after Erle Stanley Gardner died in 1970.
* TheScrappy: David Gideon, an eager young law student brought in to assist Perry. He doesn't last.
