Professor Kelvin, unable to meet his class one day, posted on the door of his lecture room a notice that read, “Professor Kelvin will not meet his classes today.”
The disappointed class decided to play a joke on the professor. Erasing the “c” they left the message to read, “Professor Kelvin will not meet his lasses today.”
The next day when the class assembled in anticipation of the effect of their joke, they were astonished and chagrined to find that the professor had outwitted them. The message was now found to read, “Professor Kelvin will not meet his asses today.”
Funny thought it may seem in this case, but the treatment has to be according to the disease. In this case the professor gave the students a taste of their own medicine!
