Clock

[Guest guest]

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 that

"jumped" ahead each minute, in a very noticeable fashion.

As it were, these clocks were also not of the most sophis-

ticated 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.

 

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 taking aim at the clock. When

he had successfully "jumped" the clock forward 1 hour, he

closed the class and collected the exam papers.
