Tonight, after about an hour of fruitless shortwave listening, I tried some ssb scanning. I scanned parts of 7000-7500 khz and 11000-11500 khz. Then I picked up a ham conversation on 3818 khz. It went something like this:
person 1: "This guy asked the mechanic to check the tire pressure. Well, the mechanic checked the pressure and it was 32 pounds in each tire. Then the guy said he wanted the car up on the lift to be sure the pressure was exact in all four tires. The guy was a teacher."
person 2: "Teachers and engineers; they're the worst."
person 3: "That's the funny thing about tires. If you add up all four tires, it's 128 pounds of air. I can lift 128 pounds, but I can't lift that car."
