The fable of The Chicken and the Pig is about commitment to a project or cause.
A Pig and a Chicken are walking down the road. The Chicken says: “Hey Pig, I was thinking we should open a restaurant!” Pig replies: “Hm, maybe, what would we call it?” The Chicken responds: “How about ‘ham-n-eggs’?” The Pig thinks for a moment and says: “No thanks. I’d be committed, but you’d only be involved!”
