Doug, tell him to bring over his laptop and then stand back and watch him look for somewhere to plug it in. When he gives up tell him it's wireless and crack open an adult beverage as he tries to find the connection. For bonus points you can rename your home router "pantera" so he thinks he's almost there. When he gives up, take him behind the car while it's idling and ask him to take a deep breath. If yours is anything like mine he will get a snoot full of sweet, unburned race fuel. You can then explain how your highly calibrated nose IS the computer. Silly kids!
