You know that old saying that there is no such thing as a stupid question? Well, there are definitely stupid questions.
The friendly, English-speaking extraterrestrial you run into outside your house is asking you to recommend the one book, movie, or song that explains what humans are all about. What do you pick?
This is an example. It is silly and a bit arrogant (of course they want to come to the US to find something to represent all of humanity.)
