Even humorless Booker you can picture standing there, just trying so hard not to.
Or at least failing to suppress a tiny smile.
The revelation that Elizabeth is Comstock's daughter and he wants her to follow in his footsteps has probably the most adorable response.
Elizabeth: Well, I want a puppy, but that doesn't mean I'm going to get one!
A moment of Fridge Brilliance is that thanks to her powers, she could get her wish fulfilled. And a moment of Fridge Horror, in at least one universe, Comstock does get his, too.
If you pay attention, seeing the difference in strength — not to mention hand size — between Elizabeth and Booker is quite amusing:
After Booker unceremoniously falls into Elizabeth's library and scares the crap out of her, while trying to calm her down he puts a hand on her shoulder. She shrugs it off and tries to strike him with her book. She's using both hands and mustering a fair bit of strength, but Booker stops both swings in their tracks with one hand and almost no effort. Here is one of the few instances that you get to compare hand sizes, too. Booker's are frigging enormous.
Another good hand comparison scene is when Elizabeth takes Booker's hand and then puts it around her throat when begging him not to let Songbird take her back.
He takes her hand in his when helping her out of the torture device in Comstock House, giving you another chance to see that Booker's hands are at least twice the size of Elizabeth's. They're literally the size of her entire face.
More strength comparison: Elizabeth finds the door to the outside of her tower, but can't make the handwheel budge an inch, even putting her whole upper body into it and bracing against the floor. Booker gets it open instantly.
When she's trying to activate a gondola, poor Elizabeth can't get the lever to move at all when she's pushing on it with everything she has. Because she didn't pull in the latch that allows the lever to move. Not her finest moment.
Speaking of Elizabeth and levers, if you listen to her trying to push that lever for any length of time, it starts to sound...pretty...wrong...
Elizabeth ganking Booker with a wrench is actually pretty funny. As is a Vox man punching him in the face just when he starts to come to. And then hanging him out of the airship to rouse him. And then throwing him out of the airship from a pretty fair height.
Booker's too busy running for his life to consider that telling someone who's never used an elevator to "call" the elevator may result in some confusion:
Booker: Call the elevator! Elizabeth:[from around the corner] What?! Booker: PRESS THE BUTTON!
As horrific as the situation itself is, Elizabeth's screaming when they fall from the top of the tower is kind of hilarious, both visually and aurally. As is both of their screaming when they fall off the skyline into the water.
Booker coughing up a lung after almost drowning sounds pretty funny. Not to mention he sounds pretty punch-drunk:
Elizabeth:[trying to help him up] Here, let me. Booker:[weakly]I'm fine. Elizabeth: You almost drowned, you need to – Booker: I said, I'm fine, just...[not sounding fine]...just, just gimme a minute. Elizabeth: ...Do you hear that? [joyously] Oh, it's music! Booker:[groggily waving a hand]Go on, I just...jus'need'a...[passes the fuck out]
One can't help but want to paraphrase that last line as, "You go on, I'll just...lie here and...die..."
Even funnier: After he finally gets up, when he asks two men if they've seen a girl around, they snidely reply, "Look at this one." "Why don't you just sleep it off, chum?" Later, Elizabeth comments, "That fall in the water did you no favors." The implication seems to be that Booker was staggering around like he was plastered. Just picture that.
There's a hilarious scene where a black man scrubbing a floor is muttering to himself about having to clean up after his employers, in clearly educated language:
"I must take any task with more than the slightest complexity, or they simply leave it in ruins for me to clean up later!"
When he realizes he has company, he immediately switches to "just an ignorant negro" mode and says he was just joking:
"Oh! Ahah! H'lo, suh! Don't you pay me no nevermind! Jus' sum foolish-ness, y'know, ha ha! Jus' monkeyshines!"
A player may have a quiet chuckle at how bad his lie is...until you rememberthe racial dynamics at play and the fact that he might well be lynched if Booker tells anyone. If you really listen to that last bit, the man's voice is shaking like mad — he's terrified. Makes you feel bad you can't reassure him.
On the note of racial dynamics, Elizabeth's ignorance of them is both charming and hilarious:
In the same vein, he's hilariously reluctant to let go of the idea that Columbia is held up by giant balloons, because he can understand giant balloons.
Elizabeth: They — well, she — invented the technology that keeps this city afloat! Booker: Giant balloons? Elizabeth: Quantum particles, suspended at a fixed point in space-time. Booker: So...not giant balloons?
And when she asks him an unrelated question a little bit later, she finds he's still stuck on that one.
Elizabeth: How do you suppose they manage that? Booker: I'll get back to you after I figure out the floating city bit.
There's also his reactions to the Luteces.
Robert: If only one of you had the ability to alter the fabric of space and time. Rosalind: Yes, that would be a blessing indeed. [They vanish.] Booker: Well. They're sarcastic.
At one point, the Luteces are engaging in some painting: Rosalind is posing, and Robert is painting. Except if you look at the canvas, Robert is painting himself.
