Two rednecks, Rod and Pete, are sitting at their favorite bar, drinking beer. Rod turns to Pete and says, "You know, I'm tired of going through life without an education. Tomorrow, I think I'll go to the Community College and sign up for some classes."
Pete thinks that's a good idea, and the two leave.
The next day Rod goes to the college and meets the dean of admissions, who signs him up for four classes: Math, English, History, and Logic.
"Logic," Rod says, "What's that?"
The dean says, "I'll show you. Do you own a weed-eater?"
"Then logically because you own a weed-eater, you must have a yard."
"That's true, I do have a yard."
"I'm not done," the dean says. "Because you have a yard, you must have a house."
"Yes, I do have a house."
"And because you have a house, you probably have a family."
"I have a family."
"I'm not done yet. Because you have a family, then logically you must have a wife."
"Yes, I do have a wife."
"And because you have a wife, then you must be a heterosexual."
"I am a heterosexual. That's amazing. You were able to find out all of that because I have a weed-eater."
Excited to take the class now, Rod shakes the dean's hand and leaves to meet Pete at the bar.
He tells Pete about his classes, how he is signed up for Math, English, History and Logic.
"Logic," Pete says, "What's that?"
Rod says, "I'll show you. Do you have a weed-eater?"
"Then you're homosexual, aintcha?."
