This man sees his new neighbor in the front yard so he goes over and decides to introduce himself.
New neighbor "I am a professor of deductive reasoning"
"Whats that"
"Well for example you have a dog house therefore you probably have a dog, since you have a dog you probably have a wife and child, and since you are married I can deduce that you are a heterosexual"
"Wow thats really amazing"

The man than goes to talk to his other neighbor
"Hey Joe you got a dog?"
"No"
"Your a fag"



Something like that
