The Avengers get attacked in a penthouse unit by an army of ninjas. In the process, Luke Cage is tossed off the roof. He's nigh invunerable of course, so he isn't hurt, but he can't fly back up to join the fight... Leading to a hilarious montage where he's just chilling in the elevator listening to the muzak till he gets back to the top, then as soon as the door opens, getting back in the action like nothing happened.
In the space of a lecture, Hope Summers goes from thinking Spider-Man is an idiot, to becoming a fangirl babbling about getting a costume like his.
Jessica Jones realizing who Spider-Man is and becoming overjoyed to find that Spidey, who was a personal idol of hers, was also the boy she used to have a massive crush on. It then unravels that Peter has no idea who she is and didn't realize that he used to go to school with Jessica Jones, superheroine and a former colleague at the Daily Bugle, and only knew her as "Coma Girl". All the while, Luke Cage is getting more and more annoyed at finding out his wife used to have a thing for Spidey, especially when she says she was 'totally in love with him'.
Luke Cage: Was it Love, or a Crush, because those are two COMPLETELY different things!
In a later issue, when Peter comments that Luke must hate him, Jessica tells him that Luke actually has a man crush on him. Peter has no idea how to respond to this.
From the end on the same arc as the above, The New Avengers, after removing a bomb that they found in Luke Cage's heart, they leave it in the house they were keeping him while he recovered and they hid from Norman Osborn. Norman sets the bomb to blow off and goes to track them down and, to his horror, the house they were hiding in, and left the bomb in, was Norman's home.
In the Illuminati Christmas special, when Santa Claus has a problem ("I can't believe the reindeer were all Skrulls!") and asks the group to let him use the Infinity Gauntlet:
Professor X: Black Bolt says "You never brought me my Speak n' Spell."
Naturally, it goes wrong—
Santa: YOU WANT THE INFINITY GAUNTLET BACK?! COME AND TAKE IT, YOU LITTLE GIRLS!
—and Namor must use all his Atlantean might to disarm Santa. With a snowball.
Namor: I am the king... of all snowball throwers.
The team believes that Victoria Hand is a double agent and was responsible for Mockingbird being shot and almost killed (she lived, thanks to a serum that turned her into a female cross between Fury and Captain America.) The problem is that none of the male members of the team want to hit her.
Mockingbird: Thankfully, I have no such issues.
She then punches Victoria so hard that she goes flying backwards.
Victoria: I can't believe you just punched me, Mockingbird!
Mockingbird: I can't believe you can't believe it.
