deductive reasoning
A man moved into a new neighborhood that was going to teach deductive reasoning at the college. When he got to his house he met his neighbor and they were talking about why he moved there.
The new neighbor told him he was going to teach deductive reasoning at the college, and his neighbor asked him what it was.
The new guy said, “Let me give you an example, I saw in your backyard that you have a doghouse.”
The neighbor said, “That’s correct.”
“Well, that leads me to believe that you have a dog.”
“Correct,” replies the neighbor.
“Well, that leads me to believe that you have children.”
“Correct again,” answers the man.
“Well, that leads me to believe that you have a wife.”
“Correct.”
“Well, that leads me to believe that you are a heterosexual.”
“Of course.”
“That is all there is to deductive reasoning, I looked at your doghouse and found out you are a heterosexual.”
“Cool!”
The next day, the man met his other neighbor at the barber shop and told him about the new teacher at the college and told him what he did.
The neighbor said, “What is deductive reasoning?”
The man said let me give you an example. “Do you have a dog house?”
The neighbor answered, “No.”
The man answered, “Fag”
