Never argue with a fool (Bull and Crocodile Fable)

 
Two bulls are standing at a river bank to drink water and looking at a log floating just at a short distance. The first tells the second that it is a crocodile. The second bull shakes its head in denial and says it is a log. The first bull picks up a stone and throws it at the log. The log does not move. The second bull reacts to it by saying, "See it is a log." The first bull again tells the second that it is a crocodile. The second again shook its head in denial and says it is a log. The first bull picks up a stick and prods the log, nothing happens, nothing moves. The second bull reacts to it by saying, "See it is a log." The first bull again tells the second that it is a crocodile. The second again shook its head in denial and says it is a log. The first bull now angry and annoyed screams at the log, splashes water on the log but to no avail nothing happens. Now, the first bull steps forward and jumps onto the log only to discover that the crocodile now just turned to eat it in a gulp and retake its position as a log. The second bull now murmurs to the third bull that "see that thing, there, is a crocodile".
