Warning: The Height of Silliness

Okay . . . this is not  thought provoking . . . but I just can't get this image out of my mind.
At work, I'm always overhearing people's conversations.
Inevitably, interspersed among all the words, is laughter.
And all I can think of, when I hear a person laugh or a group of people laugh, is hens clucking.
If an alien came to earth and facial expressions and sounds coming out of mouths had no meaning, our laughter would probably sound to them, the way the clucking of hens sounds to us.

.... like I said, this is not thought provoking.
