Abusenet

(The professor has just explained how his professors, back when he was in college, used to do complicated mathematical operations manually. He’s well-known across campus for his sense of humor.)

Professor: “I’m pretty old; I was on the Internet when it was just the geeks. No commercials, no p*rn.”

Me: “Oh please, there was p*rn on Usenet.”

(Usenet existed before the Internet.)

Professor: “Yeah, but there were no images. They were transmitted as text, and then you needed another program to transform it back. You kids don’t know how good you have it!”
