Pantomimes of lying...

In the movie “True Romance”, Christopher Walken is torturing Dennis Hopper and knows when he is being lied to. He announces that there are 17 ways for a man to give away when he is lying and 21 ways for a woman.

Is this just made up for the movie, or is there a list somewhere that says what the 17 and 21 things are respectively? I know one of them is which way your eyes look up when you are thinking about a question but that’s about all I know, and I’m not even sure which is the way they’re supposed to go, so I’m pretty useless here too.
