I got a chuckle out of a cartoon that went something like this: In the foreground, there were two departed spirits (represented as humans, with wings), standing on a cloud. In the background, there was one such departed spirit, standing next to an armored truck (presumably, filled with lots of cash). One of the two departed spirits in the foreground said to the other: "Well, it was really a nice theory. But I guess you actually can take it with you, after all."
