IJMC - Was His Name Bonk?

Possible urban legend number 4,308,219. I wonder how long until this one 
comes back around, but tied in with the wonderful story of "Bonkistry?" 
If you haven't heard of Bonkistry, go to the web site (at 
http://www.ijmc.com/ ) and click on "Search and Rescue" then enter 
"bonkistry" without the parenthesis. You'll see it's been sent out twice 
in the IJMC history...and I don't think we're yet ready for our first 
threepeat.                                                         -dave




The rules at a particular university were such that if the professor were
not present in the classroom by 15 minutes past the hour, the class was
considered a "walk" and the students were free to leave -- with no
penalties for missing a class. The rooms were equipped with the type wall
clocks which "jumped" ahead each minute, in a very noticable fashion. As
it were, these clocks were also not of the most sophisticated
construction. Some enterprising student discovered that if one were to hit
the clock with chalkboard erasers, it would cause the clock to "jump"
ahead 1 minute. 

So, it became almost daily practice for these students to take target
practice at the clock ( as it would have it, this particular professor was
not the most punctual, and the students considered him severely
"absent-minded"). A few well aimed erasers, and lo, 15 minutes were
passed, and class dismissed itself. 

Well, when the day for the next exam rolled around, the professor strolled
into the room, passed out the exams, and told them "You have 1 hour to
complete". 

The professor then proceeded to collect the erasers from around the room,
gleefully took aim at the clock. When he had successfully "jumped" the
clock forward 1 hour, he closed the class and collected the exam papers. 

Life does teach some lessons the hard way.
