A somewhat advanced society has figured out how to package basic knowledge in pill form. A student, needing some learning, goes to the pharmacy and asks what kind of knowledge pills are available. The pharmacist says: "Here's a pill for English literature." The student takes the pill and swallows it and has new knowledge about English literature. "What else do you have?" asks the student. "Well I have pills for art history, biology, and world history," replies the pharmacist. The student asks for these, and swallows them and has new knowledge about those subjects. Then the student asks: "Do you have a pill for math?" The pharmacist says, "Wait just a moment," goes back to the storeroom, brings back a whopper of a pill, and plonks it on the counter. "I have to take that huge pill for math?" inquires the student. The pharmacist replies, "Well you know math always was a little hard to swallow."
An astronomer, a physicist and a mathematician are on a train in Scotland. The astronomer looks out of the window, sees a black sheep standing in a field, and remarks, "How odd. Scottish sheep are black." "No, no, no!" says the physicist. "Only some Scottish sheep are black." The mathematician rolls his eyes at his companions' muddled thinking and says, "In Scotland, there is at least one field, containing at least one sheep, at least one side of which appears black from here."
An engineer, a physicist, and a lawyer were being interviewed for a position as chief executive officer of a large corporation. The engineer was interviewed first, and was asked a long list of questions, ending with "How much is two plus two?" The engineer excused himself, and made a series of measurements and calculations before returning to the board room and announcing, "Four." The physicist was next interviewed, and was asked the same questions. Before answering the last question, he excused himself, made for the library, and did a great deal of research. After a consultation with the United States Bureau of Standards and many calculations, he also announced "Four." The lawyer was interviewed last, and was asked the same questions. At the end of his interview, before answering the last question, he drew all the shades in the room, looked outside the door to see if anyone was there, checked the telephone for listening devices, and asked "How much do you want it to be?"

A group of blondes were willing to prove that not all blondes were dumb. They established a judges panel of people to ask the questions. On the day of the judging the people started off by asking, "What is 59 + 2?" The first blonde contestant responded by saying, "57?" The rest of the blondes said, "Give her another chance, give her another chance!" Then they asked, "What is 15 - 5?" The blonde responded, "20, right?" Once again the rest of the contestants screamed, "Give her another chance, give her another chance!" The judges decided to go easier on her and asked, "What is 1 + 2?" "Is it 3?" said the blonde. The rest of the blondes said, "Give her another chance, give her another chance!"
