Two men, Robert and Peter, are sitting at their favourite bar, drinking beer. Robert turns to Peter and says, â€You know, I`m tired of going through life without an education. Tomorrow I think I`ll go the community college, and sign up for some classes.†Peter agrees that it`s a good idea, and the two leave.
The next day, Robert goes down to the college and meets the secretary of Admissions, who signs him up for the four basic classes: Math`s, English, history, and Logic. “Logic?†Robert says. “What`s that? The secretary says, “I`ll show you. Do you own a lawn mower?†“Yeah.†“Then logically speaking, because you own a lawn mower, I think that you would have a lawn.†“That`s true, I do have a lawn.†“I`m not done,†the secretary says. “Because you have a lawn, 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 logic tells me 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 lawn mower.â€
Excited to take the class now, Robert shakes the secretary's hand and leaves to go meet Peter at the bar. He tells Peter about his classes, how he is signed up for Maths, English, History and Logic. “Logic?†Peter says, “What`s that?†Robert says, “I`ll show you. Do you have a lawn mower?â€
“No.â€
“Then you`re gay.â€
