Course in Logic

A man in his mid thrities decides that he wants to go back to school, but just to take some courses that he finds interesting. Unfortunately, when he goes to register, he finds that all the classes he had intended on taking were already too full.


Disapointed, the man figured, "Ah screw it."


The next day, the man happened to run into one of the professors who teaches at the university. The man explained his situation to the professor, to which the professor replied, "Hey, if nothing else, why not sign up for my course in Logic"


Intrigued, the man asked the professor, "What exactly do you teach in your class?"


"Well," the professor answered, "I'll give you an example of what i mean. Do you own a weed whacker?"


"Yes," the man replied. "If you own a weed whacker, then you probably have a lawn," the professor said


"Yes," the man replied.


"And if you have a lawn, then you probably own a home, right?" the professor asked.


"Yes," the man replied "And if you own a home, then you probably are married with a family, correct?" the professor asked.


"Why yes," the man replied


"And if you are married with a family, then you're in all probability heterosexual, right?" the professor asked


"Yes!" the man replied


The following day, the man decided to try out some of this "logic" at the cash clerk at the store because he was so impressed with it himself. The man askes the cash clerk, "Do you own a weed whacker?"


"No" the cash clerk replies


"Ah-hah!!", the man blurts out, "You must be gay!!"
