Jimmy Kimmel: "You don't have to eat pot. You can just smoke it."
Justin Timberlake: "As he shoots it? That's fucking stupid."
Jennifer Lawrence: "Woody, you've had so many bad ideas, but this is by far the worst one."
Ted Danson: "I think it's a fant -- [cracks up laughing] -- fantastic idea -- [cracks up laughing]."
