The second man is labeled Austria, and he says, "If you make a move, I'll." The third man is labeled Russia, and he says, "If you hit that little feller I'll." The fourth man is labeled Germany, and he says, "If you strike my friend I'll." The fifth man is labeled France, and he says, "If you hit him I'll." The sixth man is John Bull, representing Britain, and he says, "Hi there if you don't."
