Stupidity has no limits
There was once a man known with his absolute stupidity. One day, he went to the desert and suddenly he started digging as if he was looking for something when a passer-by got near him. This last asked the stupid man what he was doing. The stupid man replied to him and said :"I was looking for some coins I burried them this morning under the sand, but didn't fidn them.". the passer-by said to him that he should have left a sign. The stupid man answered confidently that he had left a mark, nevertheless it disappeared. The passer-by wondered about the mark. Then the man said: "It was a cloud in the sky."
