Introductory Chemistry at Duke has been taught for about a zillion years by Professor Воnк (really), and his course is semi-affectionately known as "Bonkistry". He has been around forever, so I wouldn't put it past him to come up with something like this.
Anyway, one year there were these two guys who were taking Chemistry and who did pretty well on all of the quizzes and the mid-terms and labs, etc., such that going into the final they had a solid A. These friends were so confident going into the final that the weekend before finals week (even though the Chem final was on Monday), they decided to go up to U Virginia and party with some friends up there.
They did this and had a great time. However, with their hangovers and everything, they overslept all day Sunday and didn't make it back to Duke until early Monday morning. Rather than taking the final then, they found Professor Воnк after the final and explained to him why they missed the final. They told him that they went up to UVA for the weekend, and had planned to come back in time to study, but that they had a flat tire on the way back and didn't have a spare and couldn't get help for a long time and so were late getting back to campus.
Bonk thought this over and then agreed that they could make up the final on the following day. The two guys were elated, relieved and very proud of their story. So, they studied that night and went in the next day at the time Воnк had told them. He placed them in separate rooms and handed each of them a test booklet and told them to begin.
They looked at the first problem, which was something simple about molarity and solutions and was worth 5 points. "Cool," they thought, "this is going to be easy." They did that problem and turned the page. They were unprepared, however, for what they saw on the next page...
WHICH TIRE? (95 points)

Dear Son, I'm writing this slow 'cause I know youcan't read fast.
We don't live where we did when you left. Your dad read inthe paper that most accidents happen within twenty miles of home, so we moved. Won't beable to send you the address as the last Arkansas family that lived here took the numberswith them for their house, so they wouldn't have to change their address. This place has a washing machine.The first day I put four shirts in it, pulled the chain and haven't seen 'em since. It only rained twice this week, threedays the first time and four days the second time. The coat you wanted me to send to you,Aunt Sue said it would be a little too heavy to send in the mail with them heavy buttons,so we cut them off and put them in the pockets. We got a bill from the funeral home, andit said if we didn't make the final payment on Grandma's funderal bill, up she comes. About your sister, she had a baby thismorning. I haven't found out whether if it is a boy or a girl so don't know if youare an Aunt or Uncle. Your Uncle John fell in the whiskeyvat. Some men tried to get him out, but he fought them off playfully, so hedrowned. We cremated him and he burned for three days. Three of your friends went off thebridge in a pickup. One was driving and the other two were in the back. Thedriver got out. He rolled down the window and swam to safery. The other 2drowned. They couldn't get the tail gate down. Not much more news this time.Nothing much happened. If you don't get this letter, please let me know and I willsend another one. Love, Ma

Charlie was visiting an old friend and his wife for dinner. When the time came to leave, his car wouldn't start, and it was too late to call the local service station.
The husband urged Charlie to stay over. There was no spare bed in the house; there wasn't even a sofa. So Charlie would have to sleep with the husband and wife. No sooner had the husband fallen asleep when the wife taped Charlie on the shoulder and motioned for him to come over to her. "I couldn't do that," he whispered. "Your husband is my best friend!" "Listen, sugar," she whispered back, "there ain't nothing in the whole wide world could wake hime up now." "I can't believe that," Charlie said. "Certainly if I get on top of you and sсrеw you, he'll wake up won't he? "Sugar, he certainly won't. If you don't believe me, pluck a hair out of his аsshоlе and see if that wakes him." Charlie did just that. He was amazed when the husband remained asleep. So he climbed over to the wife's side of the bed and fuскеd her.
When he finished, he climbed back to his own side. It wasn't long before she tapped him on the shoulder and beckoned him over again. Again he pulled a hair to determine if his old friend was asleep. This went on eight times during the night. Each time Charlie sсrеwеd the woman, he first pulled out one of the husband's аsshоlе hairs.
The ninth time he pulled a hair, the husband awoke and muttered: "Listen, Charlie, old pal, I don't mind you fuскing my wife, but for Pete's sake, stop using my аss for a scoreboard!"
A contestant on Who Wants to be a Millionaire? had reached the final plateau. If she answered the next question correctly, she would win the million dollars.
If she answered incorrectly, she would pocket only the $32,000 milestone money. And as she suspected it would be, the million-dollar question was no pushover. It was,
"Which of the following species of birds does not build its own nest, but instead lays its eggs in the nests of other birds? Is it A) the condor; B) the buzzard; C) the cuckoo; or D) the vulture?"
The woman was on the spot. She did not know the answer. And she was doubly on the spot because she had used up her 50/50 Lifeline and her Audience Poll Lifeline. All that remained was her Phone-a-Friend Lifeline, and the woman had hoped against hope that she would not have to use it. Mainly because the only friend that she knew would be home happened to be a blonde.
But the contestant had no alternative. She called her friend and gave her the question and the four choices. The blonde responded unhesitatingly: "That's easy. The answer is 'C' -- the cuckoo."
The contestant had to make a decision and make it fast. She considered employing a reverse strategy and giving Regis any answer except the one that her friend had given her. And considering that her friend was a blonde, that would seem to be the logical thing to do.
On the other hand, the blonde had responded with such confidence, such certitude, that the contestant could not help but be persuaded.
Time was up. "I need an answer," said Regis.
Crossing her fingers, the contestant said, "C) the cuckoo."
"Is that your final answer?" asked Regis.
"Yes, that is my final answer," she said, breaking into a sweat.
After the usual foot-dragging delay Regis said, "I regret to inform you that that answer is ... absolutely correct. You are now a millionaire!"
Three days later, the contestant hosted a party for her family and friends, including the blonde who had helped her win the million dollars.
"Jenny, I just do not know how to thank you," said the contestant. "Because of your knowing the answer to that final question, I am now a millionaire. And do you want to know something? It was the assuredness with which you answered the question that convinced me to go with your choice."
"You're welcome!" the blonde said.
"By the way," the winner said, not being able to contain the question anymore. "How did you happen to know the right answer?"
"Oh, come on," said the blonde. "Everybody knows that cuckoos don't build nests. They live in clocks."
