Don't take cover.

Still in Stockholm, Pickle takes a look at underground shelters. He had heard a lot about the London underground in the last Great War, W.W.II, and he wondered if the same thing applied in other countries. He was not prepared, however, at the modern usage of the tunnels as a means of transportation on trains. Even more, he was not ready to see the use modern artists had made of the ceilings (as he remarked to Pearl, "Better than the Sistine Chapel"). He may not have been right about that. After all. what does he know of modern art?
LITTLE FLY upon the train/ What's with you and your tiny brain?/ Can't you see when you're in trouble?/ It's not a movie, you have no double!
