A joke about the difference between British English and American English

Ok, let's tell a story of an Englishman and an American: an English woman lives upstairs and an American gentleman lives downstairs. They are neighbors. One day, an English woman wanted to throw dirty water from upstairs, and she shouted, "Look out!" "Who knows the American thought what happened outside, so he followed the sound and looked out, and the result was conceivable-he was splashed all over! What is the reason? It turns out that "look out" is more translated as "be careful, be careful" in British English, but it is often translated as "look out" in American English. Ha, so happy!
