Polythene Pam

"Polythene Pam" is a song written by John Lennon, credited to Lennon/McCartney, and performed by The Beatles on their album "Abbey Road".
Background.
The name 'Polythene Pam' came from the nickname of an early Beatles' fan from the Cavern Club days, named Pat Hodgett (now Dawson), who would often eat polythene. She became known as 'Polythene Pat'. She said in an interview, "I used to eat polythene all the time. I'd tie it in knots and then eat it. Sometimes I even used to burn it and then eat it when it got cold."
