Two southern Indiana farmers, George and Harold are sitting at their favorite bar, drinking beer.

George turns to Harold 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."

Harold thinks it's a good idea, and the two leave.
The next day George goes down to the college and meets the dean of admissions, who signs him up for the 2 basic classes: English and Logic.

"Logic?" George says. "What's that?"

The dean says, "I'll show you. Do you own a weed-eater?"
"Yeah."

"Then logically because you own a weed-eater, I think that you
have a yard.
"That's true, I do have a yard."

"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."

"And because you have a house, I think that you might logically 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 logically 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, George shakes the dean's hand and leaves to meet Harold at the bar.

He tells Harold about English and logic classes that he signed up for.

"Logic?" Harold says, "What's that?"

George says, "I'll show you. Do you have a weed-eater?"
"No."

"Then you're gay."
