I don’t really have one book that pops to mind. Two moves do though: “It’s a Mad, Mad, Mad World” and “Dr. Strangelove” (I sense a pattern here). And as for a song, there are two by my favorite band, REM, “It’s the End of the World as We Know It” and “Everybody Hurts”. I think I’d tell old ET that more insight would be gained from comic material than serious. And, of course, no one explains it all like Groucho Marx!
