A programmer and an engineer are sitting next to each other on a long flight from Los Angeles to New York. The programmer leans over to the engineer and asks if he would like to play a fun game. The engineer just wants to take a nap, so he politely declines and rolls over to the window to catch a few winks.
    The programmer persists and explains that the game is really easy and has a lot of fun. He explains, “I ask you a question, and if you don’t know the answer, you pay me $5. Then you ask me a question, and if I don’t know the answer, I’ll pay you $5.” Again, the engineer politely refuses and tries to get to sleep.
