Firstly, Paulie's initial reaction, clearly disturbed by the robot. Then he figured out how to change it's voice and mannerisms to reflect that of an ideal wife of his. He lampshades that too.
"When I come back, that thing will be like my wife."
Apollo's reaction to seeing that Robot. His face seals it. In fact, it's entirely possible Carl Weathers wasn't told about the robot beforehand to get that reaction.
"...Umm, anyway, as I was saying"
Drago, Ludmilla, Koloff, Rocky, Paulie and Adrian's extremely confused reactions at Apollo's entrance on the ring, complete with James Brown leading a song-and-dance number.
It helps that Dolph Lundgren never saw the set before they shot the scene. His confusion was real.
After that heart warming speech Paulie gave to Rocky, and listening to the Russian National Anthem, Paulie follows up the speech with this exchange.
Paulie: Remember when I said I wanted to be like you? Rocky: Yeah? Paulie: Forget it. Rocky: ...Thanks, Paulie.
The pre-fight press conference for 'Creed vs. Drago' has several funny moments, mainly from Apollo.
When Drago is asked a question and stays silent, Apollo says "the man's tongue didn't come through customs!"
Even Rocky gets in on the humor. When he is asked about how Creed should fight Drago, he answers "the first thing Apollo needs is a ladder!"
After the press conference escalates into a shouting match between Apollo and Drago's handlers, Apollo storms off with Rocky, asking calmly under his breath how he did. Rocky said it was a little loud but he liked it.
Rocky Jr. gets some digs in on his old dad:
Rocky: I don't want you to use your head for a punching bag like I do. Rocky Jr.: Your head doesn't look like a punching bag. Rocky: (genuinely touched) No? Oh, that's very nice. Rocky Jr.: It looks more like a catcher's mitt! Rocky: Oh, a wise guy, huh?
Of course it follows Ludmilla's bald-faced lie that her husband never took performance enhancing drugs, but her little joke about Popeye and spinach garners at least a few little chuckles. And Ivan's stone-faced expression just gives it that special off-kilter kick to be funny in a strangely Narmish kinda way.
