Whenever Yosemite Sam is preparing to shoot his arch-nemesis, Bugs Bunny, he tells him: "Now say your prayers!" Yosemite Sam then gives the rascally rabbit time to pray which (unfortunately for Sam), gives Bugs enough time to thwart Sam's attempt to shoot him.
Wikipedia's entry on Yosemite Sam referred to this habit, mentioned, that the character "consistently displays an odd respect for religious conventions."
