Those teachers are so smart :-)

Those teachers are so smart --

Introductory Chemistry at Duke has been taught for about a zillion
years by Professor Bonk (his real name), and his course is
semi-affectionately
known as "Bonkistry". He has been around forever.

Anyway, one year there were these two guys who were taking chemistry
and who did pretty well on all of the quizzes and mid-terms and labs,
etc., such that going into the final they had a solid A.

These friends were sooooo 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 hang-overs
and everthing, 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 Bonk after
the final and explained to him why there 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 ad 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.

They studied that night and went in the next day at the time Bonk
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 then turned the page. They were unprepared, however, for what
they saw on the next page......

Which tire??? (95 points)!!
