Parable Of The Onion 

Somewhere at the start of Shrek 1, Donkey is being a dick and Shrek stars chatting shit about onions. He tells Donkey that "there is more to ogres than people think" and says that ogres are like onions, they have layers. This is called the 'Parable Of Onion'.

(DISCLAIMER: DO NOT USE IN R.S EXAMS. YOU WILL NOT GET THE MARKS)

"Shrekism is a religion based upon the 'Parable Of The Onion'"

"Ogres have layers! Onions have layers. You get it? We both have layers." - The Great Shrek (Peace be upon him).
