Walk the Line

In the movie/bio of Johnny Cash there is a scene where Jerry Lee Lewis says:


God gave us a great big apple, see, and He said don't touch it. 
He didn't say touch it once in a while; 
He didn't say take a nibble when you're hungry; 
He said don't touch it! 


Don't think about touchin' it, 
don't sing about touchin' it, 
don't THINK about singin' about touchin' it!
