I wait .....
"What???? Didn't you find that funny?", I ask
And he came back and started reading it again, asking where the humor was. "You don't think a 10 meter (33 foot wide) baboon is funny?" He had read the 'baboon' as 'balloon' throughout the whole article.
We later came to the conclusion that we both have something very wrong with our brains but in the exact opposite direction. I told him the next time he goes to the zoo, tell your wife, "Look Honey, can I have a balloon?!?!?"
Brownian Motion from Wikipedia.com
Consider a large balloon of 10 meters in diameter. Imagine this large balloon in a football stadium or any widely crowded area. The balloon is so large that it lies on top of many members of the crowd. Because they are excited, these fans hit the balloon at different times and in different directions with the motions being completely random. In the end, the balloon is pushed in random directions, so it should not move on average. Consider now the force exerted at a certain time. We might have 20 supporters pushing right, and 21 other supporters pushing left, where each supporter is exerting equivalent amounts of force. In this case, the forces exerted from the left side and the right side are imbalanced in favor of the left side; the balloon will move slightly to the left. This type of imbalance exists at all times, and it causes random motion. If we look at this situation from above, so that we cannot see the supporters, we see the large balloon as a small object animated by erratic movement.
