A redneck decides to broaden his horizons so he enrolls at a local college. When it comes time to sign up for classes he has no idea what to take. He stops a professor and asks what he would recommend. The professor says "you should take logic classes."
"What the hell would I use that fer?" asks the redneck.
"I'll show you. Do you own a rake?"
"Sure do." the redneck replies.
"OK. I can then infer that since you own a rake you have a yard. Am I right?"
"Hell, that's right!"
"I can further deduce that since you have a yard you must own your own home."
"Wow! That's right!"
"Since you own your own home and look to be middle age I'll bet you have a wife."
"Heck yeah, I do!"
"Then I can deduce that you are a heterosexual. Correct?"
"Damn straight!"
The redneck is so impressed he signs up for all the logic classes available. Then he goes to the bar to tell his friend.
"Logic? What the hell you takin' that for?" the friend asks.
"I'll show you. Do you own a rake?"
"No." says the friend.
"Then you're a queer."
