The guy John Adams couldn't stand

J.L. Bell introduces us to Robert Treat Paine, more specifically, John Adams's disgust for his fellow signer of the Declaration of Independence:

That evening at Put[nam]s, he called me, a Numbskull and a Blunder Buss before all the Superiour Judges. I was not present indeed, but such expressions were indecent and tended to give the Judges a low Opinion of me, as if I was despized by my Acquaintance. He is an impudent, ill-bred, conceited fellow.
