Grimace from McDonald's is our lord and savior. Drink his almighty Grimace Shake. Worship only Grimace. Worship no one else. If you do, he'll hunt you down. We must give Grimace a sacrifice. Give him one of those Chicken McNuggets. Give him the fries. Give him the Big Mac, and give him ourselves. Give him Ronald McDonald.
