John started his car, then got out to squeegee the windshield, and locked himself out. He shut the car off by crawling underneath and disconnecting the spark plug wires, shocking himself three times and banging his head on the front bumper. Was there a better way to turn off the engine? Yes, Tom and Ray say John could have stuffed the tailpipe with something like a potato, and as long as there were no leaks in the exhaust, it would have done the trick.
