Two Newfoundland fishermen, Jim and Bob, are sitting at their favorite
bar, drinking beer. Jim turns to Bob 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."

Bob agrees that it's a good idea, and the two leave.
The next day, Jim 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?" Jim says. "What's that?"
The dean 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 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 logic tells me you must be
heterosexual."

"I am a heterosexual. That's amazing, you were able to find out all of
that because I have a lawn mower."

Excited to take the class now, Jim shakes the Dean's hand and leaves to
go meet Bob at the bar.
He tells Bob about his classes, how he is signed up for Math, English,
History, and Logic.
"Logic?" Bob says, "What's that?"
Jim says, "I'll show you. Do you have a lawn mower?"

"No."
"Then you're a queer.
