Do you like NHL?
When the guy went to university he met a recent graduate who advised him to take a logic course.
"But what is logic?"
"With the help of logic you can draw conclusions about certain facts out of other facts. Here's an example: do you have a lawn mower?"
"Yes, I do."
"So I conclude your yard is grassy."
"Yes, it's grassy."
"It is obvious then that you have a house too."
"Sure, I do have a house."
"So you are a married man."
"Yes, I am."
"Do you also have children?"
"Yes, I have children."
"So I conclude you are heterosexual."
"Yes, I am heterosexual. Logic is truly amazing. You can tell I'm heterosexual because I have a lawn mower."
When the guy next came across an acquaintance of his he immediately suggested that he study logic.
"Why? What's logic?" the acquaintance asked.
"With the help of logic you can draw conclusions about certain facts out of other facts. Here's an example: do you have a lawn mower?"
"No."
"Then you are gay."
