Joke

Working as a computer instructor for an adult-education program at a community college, I am keenly aware of the gap in computer knowledge between my younger and older students.
My observations were confirmed the day a new student walked into our library area and glanced at the encyclopedia volumes stacked on a bookshelf.
"What are all these books?" he asked.
Somewhat surprised, I replied that they were encyclopedias.
"Really?" he said. Someone printed out the whole thing?"
