Add Another Quote and Make It a Gallon
An exchange between Garson Kanin (first line) and Billy Wilder (last) in Garson Kanin's “Hollywood”:
“I quoted. ‘Work strengthens us, pleasure consumes us. Let us choose.’ You know who said that?”
That cracks me up. On some level, I think of shenanigans like this. Too often people consider the quoter the trump card rather than the quote. It's only gotten worse in the Internet age.
Still, not a bad quote. But only if your work isn't repetitive and soul-draining.
