An eccentric philosophy professor gave a one question final exam after a semester dealing with a broad array of topics.

The class was already seated and ready to go when the professor picked up his chair, plopped it on his desk and wrote on the board: “Using everything we have learned this semester, prove that this chair does not exist.”

Fingers flew, erasers erased, notebooks were filled in furious fashion. Some students wrote over 30 pages in one hour attempting to refute the existence of the chair. One member of the class however, was up and finished in less than a minute. Weeks later when the grades were posted, the rest of the group wondered how he could have gotten an A when he had barely written anything at all.

His answer consisted of two words: “What chair?”

The following is (supposedly) from the US Government Peace Corps Manual for its volunteers who work in the Amazon Jungle. It tells what to do in case you are attacked by an anaconda. Now an anaconda is the largest snake in the world. It is a relative of the boa constrictor, it grows to thirty-five feet in length and weighs between three and four hundred pounds at the maximum.

This is what the manual said:

1. If you are attacked by an anaconda, do not run. The snake is faster than you are.
2. Lie flat on the ground. Put your arms tight against your sides, your legs tight against one another.
3. Tuck your chin in.
4. The snake will come and begin to nudge and climb over your body.
5. Do not panic.
6. After the snake has examined you, it will begin to swallow you from the feet and – always from the end. Permit the snake to swallow your feet and ankles. Do not panic.
7. The snake will now begin to suck your legs into its body. You must lie perfectly still. This will take a long time.
8. When the snake has reached your knees slowly and with as little movement as possible, reach down, take your knife and very gently slide it into the side of the snake’s mouth between the edge of its mouth and your leg, then suddenly rip upwards, severing the snake’s head.
9. Be sure you have your knife.
10. Be sure your knife is sharp.
