A guy was about to finish up his last few classes to get his degree and had to take one more elective. After looking through the catalog for something that looked easy, he spotted a class called "Logic". He decided to ask the professor who taught the class what it was about and if he could sign up.
"What's the class about?"
"Logical thinking and Extrapolation"
"Can you explain that?"
"Well, here's an example. Do you have a weed-eater?"
"Yes, I do."
"Well, I can extrapolate from that that you own your own home, correct?"
"Yes, I do. That's amazing"
"And can I also assume from the fact that you own your own home that you're married?"
"Yes! Yes, I am".
"And from that I can assume that you are a heterosexual, correct?"
"Wow! Yes, I am. Can I take this class?"
Well, after a few weeks of the class the student was having a beer with a friend. His friends asked...
"So how's school?"
"Great! I'm almost done."
"What are you taking right now?"
"A class on logic."
"Really? what's that all about?"
"Well... do you have a weed-eater?"
"No. No I don't"
"What're ya, gay?"
