Made funnier by the fact that Adams actually was a lawyer.
As was Dickinson.
Also fribble is an actual word along with piddle, twiddle, pish posh, gay, and queer.
Adams' morose worry that for all his effort to make America free, his contributions would never be known:
Franklin: Don't worry, John. The history books will clean it up. Adams: It doesn't matter. I won't be in the history books anyway, only you. Franklin did this and Franklin did that and Franklin did some other damn thing. Franklin smote the ground and out sprang... George Washington, fully grown and on his horse. Franklin then electrified him with his miraculous lightning rod and the three of them - Franklin, Washington, and the horse - conducted the entire revolution by themselves. Beat Franklin: I like it.
Pretty much everything Ben Franklin says. He was pretty much our nation's first Deadpan Snarker.
Franklin: (to arriving delegate Dr. Lyman Hall) "What's the matter? Haven't you ever seen a Great Man before?" And Adams: Wake up, Franklin, you're going to New Brunswick! Franklin: (Half asleep) Like Hell I am. What for? Hopkins: The whoring and the drinking! (Franklin gets up and marches off right behind Adams)
Jefferson's initial failure to write the Declaration.
Adams: Do you mean to tell me that it is not yet finished?
Jefferson: No, sir. I mean to say that it is not yet begun.
Adams: Good God! A whole week! The entire earth was created in a week!
Jefferson: Someday, you must tell me how you did it.
Adams: Disgusting. Look at him, Franklin! Virginia's most famous lover!
Jefferson: Virginia abstains.
The scene where he's trying to write: writes a little, then crumples up the paper. then he writes even LESS on the next sheet before crumpling it, and finally he just stares at the next one before crumpling it.
Adams realizing that Jefferson and his wife were having the 18th century equivalent of a booty call:
Adams: You mean they're going to... in the middle of the afternoon??
Franklin: Not everybody's from Boston, John!
"This is a REVOLUTION, dammit! We're going to have to offend SOMEBODY!"
Adams finally brings up one last quibble about the Declaration: arguing that the word is "unalienable" not "inalienable":
Jefferson: I'm sorry, Mr. Adams, but "Inalienable" is correct. Adams: I happen to be a Harvard graduate, Mr. Jefferson. (some laughs from congress) Jefferson: Well, I attended William & Mary. (more cheers) Hancock: Mr. Jefferson, will you concede to Mr. Adams' request? Jefferson (relishing the moment): No, sir, I will not. Adams (realizes he can't win): Oh, very well, I withdraw it! Franklin: Oh, good for you, John!
Adams mutters under his breath he'll talk to the printer later and change it then.
Adams being a combination of extremely awkward and irritated when Martha arrives and she and Jefferson start kissing so passionately they become oblivious to anything else.
"[pointedly looking away from the scene] Jefferson, kindly introduce me to your wife!"
John and Abigail's first song in "Piddle, Twiddle, and Resolve," both of them completely unimpressed with the other's problems:
In response to the long list of things going wrong at home, Adams replies "Madam, what else is new?"* Granted, in Real Life he was more worried about these things.
When John demands to know why the ladies aren't making saltpeter, Abigail points out that he didn't tell them how it's done.
John: By treating potassium chloride with sodium nitrate, of course! Abigail:Oh yes, of course!
That this is met with Abigail's "more urgent" problem: a pin shortage in Massachusetts, which she demands that John resolve before she sends him saltpeter—and wins.
"The Lees of Old Virginia." Franklin's wheedling, Lee serving a large helping of ham quite generous-Lee, and Adams as a wholly unwilling participant in the entire number. After it's over, he calls in "the most revolting display I ever witnessed." Not Lee, Franklin, for inciting it.
It gets even better in the movie: when Lee returns for his unexpected reprise, Adams winds up falling into the fountain.
The argument over whether the national bird is going to be an eagle, a dove, or a turkey.
