Man approaches to greet a new neighbor who is just moving into the house next door and asks what he does for a living. Neighbor 1: I am a professor at the University, I teach deductive reasoning. Man: Deductive reasoning? What is that? Neighbor 1: Let me give you an example. I see you have a dog house out back. By that I deduce that you have a dog. Man: That's right. Neighbor 1: The fact that you have a dog, leads me to deduce that you have a family. Man: Right again. Neighbor 1: Since you have a family I deduce that you have a wife. Man: Correct. Neighbor 1: And since you have a wife, I can deduce that you are heterosexual. Man: Yup. Neighbor 1: That is deductive reasoning. Man: Cool. .....Later that same day... Man: Hey I was talking to that new neighbor next door. Neighbor 2: Is he a nice guy? Man: Yes, and he has an interesting job. Neighbor 2: Oh, yeah? What does he do? Man: He is a professor of deductive reasoning at the University. Neighbor 2: Deductive reasoning? What's that? Man: Let me give you an example. Do you have a dog house? Neighbor 2: No. Man: Queer!
