Two young guys were picked up by the cops for smoking dope and appeared in court on Friday before the judge. The judge said:
"You seem like nice young men, and I'd like to give you a second chance rather than jail time. I want you to go out this weekend and try to show others the evils of drug use and get them to give up drugs forever. I'll see you back in court Monday."
Monday, the two guys were in court, and the judge said to the 1st one, "How did you do over the weekend?"
"Well, your honor, I persuaded 17 people to give up drugs forever."
"17 people? That's wonderful. What did you tell them?"
"I used a diagram, your honor. I drew two circles like this...
o O
...and told them this (the big circle) is your brain before drugs and this (small circle) is your brain after drugs."
"That's admirable," said the judge. "And you, how did you do?", he asked the second boy,
"Well, your honor, I persuaded 156 people to give up drugs forever."
"156 people! That's amazing! How did you manage to do that?!?", "Well, I used a similar approach. (draws two circles)
O o I said (pointing to the small circle) "this is your аsshоlе before prison, ..."
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)
