Two rednecks, Larry and Doug, are sitting at their favorite bar drinking beer. Larry turns to Doug and says: “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.” Doug thinks it's a good idea, and the two leave.
The next day, Larry goes down to the college and meets the Dean of Admissions, who signs him up for the four basic classes: math, English, history, and logic. “Logic,” Larry says: “What's that?”
The dean says: “I'll give you an example. Do you own a weed eater?”
“Yeah,” Larry replies.
“Then, logically speaking, because you own a weed eater, I think that you would have a yard,” the Dean explains.
“That's true, I do have a yard,” Larry says.
“I'm not done,” the Dean says: “Because you have a yard, I think logically that you would have a house.”
“Yes, I do have a house,” Larry says.
“And because you have a house, I think that you might logically have a family,” the Dean continues.
“Yes, I have a family,” Larry replies.
“I'm not done yet,” the Dean says: “Because you have a family, then logically you must have a wife. And because you have a wife, then logic tells me you must be a heterosexual.”
“I am a heterosexual!” Larry exclaims: “That's amazing. You were able to find out all of that because I have a weed eater.”
Excited to take the class now, Larry shakes the Dean's hand and leaves to go meet Doug at the bar. He tells Doug that he signed up for math, English, history, and logic.
“Logic?” Doug says: “What's that?”
Larry says: “I'll give you an example. Do you have a weed eater?”
“No,” Doug replies.
“Then you're a queer!”
