Here's a joke:
A man just moved into a house and is talking with his new neighbour.
Neighbour 1: "Hi, there, new neighbour, it sure is a nice day to be moving."
New Neighbour: "Yes, it is and people around here seem extremely friendly."
Neighbour 1: "So what is it you do for a living?"
New Neighbour: "I am a professor at the University, I teach deductive reasoning."
Neighbour 1: "Deductive reasoning, what is that?"
New Neighbour: "Let me give you an example. I see you have a dog house out back. By that I deduce that you have a dog."
Neighbour 1: "That is right."
New Neighbour: "The fact that you have a dog, leads me to deduce that you have a family."
Neighbour 1: "Right again."
New Neighbour: "Since you have a family I deduce that you have a wife."
Neighbour 1: "Correct."
New Neighbour: "And since you have a wife, I can deduce that you are heterosexual."
Neighbour 1: "Yup."
New Neighbour: "That is deductive reasoning."
Neighbour 1: "Cool."
Later that same day
Neighbour 1: "Hey, I was talking to that new guy who moved in next door."
Neighbour 2: "Is he a nice guy?"
Neighbour 1: "Yes, and he has an interesting job."
Neighbour 2: "Oh, yeah what does he do?"
Neighbour 1: "He is a professor of deductive reasoning at the University."
Neighbour 2: "Deductive reasoning, what is that?"
Neighbour 1: "Let me give you an example. Do you have a dog house?"
Neighbour 2: "No."
Neighbour 1: "Fag."
