Piet and Koos, are sitting at their favorite bar, drinking beer.

Piet turns to Koos 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."

Koos thinks it's a good idea, and the two leave. The next day, Piet goes
down to the college and meets dean of Admissions, who signs him up for
the four basic classes: Math, English, History, and Logic.

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

The dean says, "I'll give you an example. Do you own a weed eater?"

"Yeah."

"Then logically speaking, because you own a weed eater, 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."

"Yes, I have a family."

"I'm not done yet. 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. That's amazing, you were able to findout all of
that because I have a weed eater."

Excited to take the class now, Piet shakes the Dean's hand and leaves to
go meet Koos at the bar. He tells Koos about his classes, how he is
signed up for Math, English, History, and Logic.

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

Piet says, "I'll give you an example. Do you have a weed eater?"

"No."

"Then you're a moffie .........."
