We were doing fine until the last four questions, the first of which led to contentiousness and recriminations and eventual apologies.  If it wasn't phrased more craftily than below, there are two possible answers.  We missed all of these:

How many levels are in Maslow's hierarchy of needs ?


Who was the longest-serving U.S. Supreme Court justice ?

What English name, possibly deriving from the Hebrew for "to behold", was the first-or second-most popular female baby name in the United States from 1981 to 1998 ?

What U.S. president was featured on a $5000 bill ?

It's 5 in the hierarchy, right? Food & water, shelter & safety, coffee, chili cheese fries, and self-actualization?



If I don't know the answer for a U.S. Supreme Court justice, I'd guess Felix Frankfurter, but because it's an amusing name, not because I think it's the correct answer. Other good justice trivia: Taft was both a U.S. President and a U.S. Supreme Court justice (not at the same time, obvs). James Wilson was jailed for debts while a sitting U.S. Supreme Court justice.
I just read (part of) “The Lost Founder” about Wilson, and it’s a wild story. He fled to the southern states to avoid his creditors, but kept working as a judge along the way.
