These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Vietcong Colonel Siue in the season 4 finale "The Sound of Thunder" has no trouble attacking villagers, just for housing the A-team. His Kick The Dog moment is when he horribly kills General Fullbright, despite the latter did nothing to him (personally at least).
Crazy Awesome: Each and every member of the team to some extent, but Murdock personifies this trope. "Howlin' Mad", right?
"Funny Aneurysm" Moment: A joke by Murdock in "Water, Water Everywhere" where he brags about his matchmaking capabilities references his success with Princess Diana and Prince Charles, at the time recently married.
The season 3 episode "The Big Squeeze" has Hannibal faking his own death and funeral in order to trick a racketeer. Now try to watch that scene now that George Peppard died in 1994.
Ho Yay: These days, you could look back and spot quite a bit of it, especially between Hannibal and Face, Face and Murdock, and Murdock and B. A. (which might border on Foe Yay at times).
In the Season 1 episode "Till Death Do Us Part," Murdock has to help save the client from her evil fiancée by wearing her wedding dress and walking down the aisle. He spends the rest of the episode feeling broken up over leaving the groom at the altar and even writes the man a letter to apologize. It all culminates in these lines:
Hannibal: Murdock, he was lucky to have you for as short a time as he did. Murdock(sniffling): That's beautiful of you to say, Colonel.
Strongest example has to be in the third episode of the 5th season - Murdock is so happy to see B.A. that he kisses him all over his face, and when Stockwell tells them they have to move to Virginia, Murdock says "Virginia, that's so far away. B.A. and I, we just got back together." Awwww.
Memetic Mutation: One of the earliest Internet memes was the "Mr. T versus" comic, which mostly involved editing stills from The A-Team and borrowed heavily from B.A.'s character to describe Mr. T (like claiming Mr. T also had a fear of flying). Some of them also included Murdock to be pitied by Mr. T.
I LOVE IT WHEN A PLAN COMES TOGETHER.
Narm: Hulk Hogan being casually referred to as "Hulkster" in "Body Slam".
The Scrappy: Frankie Santana, a fifth member added to the cast during it's last season. His character is almost the same as that of both Face and Murdock. He's Casanova like Face and especially crazy like Murdock. In the first seven episodes of the same season, the writers thought it was a good idea to make Frank a new Murdock to BA (while the real Murdock has been Flanderized into a really sane man). BA even said/make the usual things/threats to Frank he usually says to Murdock. The writers seems to realize it didn't work, so they teamed up Frankie more with Face and Murdock for the remainder of the series.
General Hunt Stockwell, for apparently taking over the show, as well his attitude towards the team. Despite being played perfectly by Robert Vaughn, he still remains a Scrappy to many.
Tawnia Baker. While Amy did have some popularity, Tawnia was nothing but a boat anchor getting shoehorned into every situation and desperately wanting to be on the team for no reason. Despite the Character Shilling she got, the actors themselves clearly don't want anything to do with her.
Marla Heasley, the actress, later explained that from the first day she showed up on set, she was treated with hostility by George Peppard just for being a woman on what the cast felt should be an all-male ensemble. Melinda Culea, who played Amy, told a similar story of her own departure being essentially forced on her for daring to ask for something more to do and Peppard pushing heavily for her to be ejected. Both character existed entirely because the network was concerned about airing a show with so many male main characters and zero women. Eventually, Peppard won out, but one last attempt was made at the end of season 4 to integrate Tia Carrere's character of "Tia" into the show, but Carrere dropped out due to her obligations to General Hospital instead.
Values Dissonance: It's hard to imagine Hannibal getting away with yellowface or blackface disguises anymore as he did early in the show's run. The network seemed to be aware of this on some level, as the "Mr. Lee" disguise only appeared once on screen and disappeared from the opening credits past the first season. B.A. made a crack about the low quality of Hannibal's blackface disguise in the very episode in which it appeared, though even the joke itself comes off as bad taste now.
It's also hard to imagine Hannibal and Face being able to utter as many sexist comments as they did back then.
Main characters on network television aren't generally allowed to smoke on-screen anymore (at least not as often as Hannibal), especially when the show is aimed at children.
B.A. thought there was something wrong with the implication that they were gay in "There Goes the Neighborhood".
In the same episode where Hannibal is in blackface, while undercover Murdock mock-threatens to rape a woman associated with the bad guys.
Acceptable Ethnic Targets: Played With and nearly invoked, as the Big Bad is apparently an Arabian business man (shemagh and huge-ass beard)... only to be neatly subverted when it is revealed that the "Arab" behind everything is actually General Morrison in disguise.
Freud Was Right: In the Too Kinky to Torture scene with Pike where he is giving his would-be assassin tips on how to assemble the gun and shoot him, the way the would-be assassin holds the gun is sort of...odd.
Stop Helping Me!: Face was actually upset Hannibal broke him out, as because he is so charismatic he was living a decent prison life including a tanning booth, a hot female guard for a "companion" and was due for a parole hearing in a week.
Though that dropped the second he realized Hannibal needed him and could get the charges cleared.
