Two men were discussing which one of them owned the best horse. To find out, they decided to organize a match. Because both of the men did not like to loose, they agreed on doing a ride as slow as possible. The last horse which would pass the finish would be the best one. The match started, but of course it did not proceed at all. After several hours the horsemen jumped of their horses and agreed upon something. After this short talk they jumped back on the horses and went with full speed to the finish. What did they agree upon?

Susan is in the final of a match at the olympic games. At the moment she reaches the finish, all the other contestants are behind her back. She did not play unfair and did also not use doping, but she does not get the gold medal? Why is that?

At a particular ice cream van two types of ice creams are being sold. The small one costs 1 dollar, the big one 2 dollars. Marsha puts an amount of 2 dollars one the counter and gets without asking the big ice cream. Martha also would like to have an ice cream. She also puts an amount of 2 dollars on the counter. Then the ice cream seller asks her which ice cream she would like to have. Assuming that the persons do not know each other, how can you explain their behavior.
