I knew this guy who was grossly arrogant. He was also, unfortunately, really frickin' smart. One of those *took naps in class but still heard enough, and since he retained basically everything he heard he got straight As* guys. His people had sufficient money so they sent him to college, where he continued to take naps and get straight As, after, of course, taking the SATs and getting higher scores than anyone he knew. Football fan that on Monday would 'discuss' Sunday's games play by play, and of course could point out every error made by coaches, players, or even the announcers, and back up his assertions by quoting stats from prior seasons off the top of his head.
Pretty close to universally despised throughout life, then dropped out of school and joined the navy...where he encountered a bunch of people more or less like himself. Most of us were college dropouts of the ran out of money or just got board sorts. We all got maximum marks on the military's entrance test, then we all passed a test that was only given to people who got that top mark. We all then went to some sort of navy trade school where we were required to finish in the top two thirds of the class to stay in our program, which sounds easy enough until you realize that more than two thirds of the people in the class are in our program so a couple losses are guaranteed...more if someone slipped through the net and got in the class from a different program. Then if we got through that we got sent to our own program school, which had an attrition rate for that very seldom dipped below fifty percent. To say he was among the better minds the navy could find is not a falsifiable claim. Yet he was still arrogant to the point where shooting him out a torpedo tube was a common fantasy discussion, because he had no doubt that he was far and away the smartest of us.
Then this navy campus rep came to the boat, and a handful of guys decided to take the opportunity to get a degree before they got out, including this guy. Most, of course, blew it off before they really got started, but this guy and one other guy got as far as signing up for a bunch of 'college level examination program' tests. Sit for a three hour exam, get six credits of the basic core requirements out of the way...if you pass. Accredited universities don't skip the registration fees on those core curriculum courses just because you show up, the tests aren't easy. The navy campus rep proctors the tests and has the room for six hours, and guys from all over the base, different ships, whatever are there...like twenty guys. So these two guys, arrogant and his pal, walk in having signed up for four tests.
The rep has said that if they have the time after two they can take a third, she'll time them individually rather than making them use the two three hour blocks and still have two tests for the next testing cycle. Of course Mr Arrogant and his sidekick blow through all four of their tests, with plenty of time to spare, and the proctor basically shakes her head assuming they have wasted their time and effort. Much to Mr Arrogant's satisfaction, he gets to point out that he waited almost fifteen minutes for the sidekick to finish. Then they come back to the boat. In telling the rest of the guys about how easy it was and how getting a degree is gonna be a breeze, a little tension pops up between our arrogant pair. They decide nothing will settle their differences like a bet, though the sidekick doesn't really express much interest.
Terms of the bet as laid down by Mr Arrogant: each test has two subsection scores and a final score; three scores per test, twelve overall. Whoever gets the most high scores wins, loser buys three fifths of winner's choice, they drink one together and each have one to dispose of at their leisure. Since they actually live off base in the same apartment complex this is just a question of who buys liquor they would likely have drunk anyway, so it's obvious this is just a brag bet, not a stakes bet. The sidekick sort of half heartedly pointed out that there could be a tie and suggested maybe using total score as a tiebreaker, and Mr Arrogant scoffed and said that if by some outrageous shocking turn there was a tie he'd call it a loss...in fact he'd spot the sidekick two points. Most of us forget all about the bet long before the scores come in, so most of us never figured out what happened to Mr Arrogant. A lot of people thought the sidekick, who was really his only friend, might have lost patience with him and actually beat him up. But the truth is that getting beat up wouldn't have had any impact on him, probably. And there was definitely an impact. Mr Arrogant actually became a very decent human being, had lots of friends, got married, and by all indications lived happily ever after.
What changed the course of Mr Arrogant's life was the sidekick beat him across the board, twelve to nothing. By wide margins. At a contest of his own devising.
