Has anyone mentioned the "Masturbation Song"?

               Last night I contemplated masturbation,
               Oh wasn't it grand,oh wasn't it grand?
               Left hand, right hand, jerk it in and out,
               Left hand, right hand, flip it all about!
               Some will maintain that sexual intercourse is grand
               But for personal satisfaction I would rather use my hand!
   
   I heard this sung many years ago by a schoolteacher originally from Wales.
