Aliens and farmers

One day, an alien met a farmer. But they don't understand each other's language, but they can express it by gestures.

The farmer made a gesture of "down", the alien made a gesture of "up", the farmer made a gesture of "fifty", the alien made a gesture of gun, the farmer made a gesture of "five" and the alien made a gesture of "three".

The farmer came home and said to his wife, "I met a very strange man." I said potatoes grow from the soil. He said potatoes fell from the sky. I said we have five big watermelons for fifty dollars. He said they had three watermelons for seven dollars. "

The alien returned to his planet and said to his brother, "I saw a strange man today." I said I flew down from the sky. He said he came out of the dirt. I said I shot three people with a gun. He said that he personally killed 50 people. "

Without effective communication, everyone misunderstood each other's meaning.
