That reminds me of the following story. Two men are sitting in a bar. "What do you do for a living?" asks one. "I am a university professor" replies the other. "What do you teach?" asks the first. "Logic" replies the second. The other guy looks nonplussed. "What's that?" he asks. "It is the art of drawing proper conclusions from the facts you know" replies the university professor. The other guy still looks nonplussed, so the university professor says: "Let me show it to you on an example. Do you have a dog?" "Yes" replies the second guy. "Judging from the fact that you look tough and mean, I gather it is a big dog" says the professor. "You're absolutely right" says the guy. "Since it is a big dog" continues the professor, "I think you must have a yard to let it out." "True again" says the guy. "From that we can easily conclude that you also have a large house." "You're right again" replies the guy. "But that is not all" continues the professor "I also conclude that you must have a mortgage on it." "How did you know that?" exclaims the guy? "That was easy" replies the professor "since you have a big yard, your house must also be big, and you do not look like someone who can afford a big house without borrowing money." "But there is more" says the professor "I also gather that you must be married." "That is truly amazing" replies the guy "how did you get that?" "That is a no brainer" says the professor "You must have a family to qualify for a mortgage. What bank would loan any money to a single guy with a dog?" "You are right again" says the guy. "And that tells me" the professor continues "that you heterosexual." "Wow, that is really amazing how you could guess all that stuff" said the guy.
After the professor left the bar, the bar tender approaches the guy who talked to him and asks "Who was that guy?" "A university professor" "Really?" asks the bar tender "And what does he teach?" "Logic" answers the guy. "What's that?" asks the bar tender. The guy, eager to demonstrate his newly acquired skill says "Let me show it to you on an example. Do you have a dog?" "No" replies the bar tender. The guy looks at him and says in disgust "Homo!"
