TOM: I know it had to do with electricity and rain.

RAY: There you go. That's good enough.

TOM: And my hair was involved.

RAY: Here it is.

TOM: Yeah.

RAY: We had a car in the shop the other day that was making a very common noise that a spark plug wire or bad coil or some electrical discharge makes. It's a snapping sound. Anyone that has heard this that has a car that is running on five cylinders instead of six. My brother's Dart sounds like this all the time. You sit there and listen to the idle and you hear snap, snap, snap, snap! So every minute or two you would hear this noise and the noise was loud enough that the driver sitting in the car with the radio off could hear the noise, although it was not accompanied by an engine miss. Nevertheless, he was bothered by it. We were convinced that it had something to do with a misfire that somehow a spark was jumping to ground. In fact, I will give you this hint, it was. It was a spark jumping to ground, but we couldn't find it. We checked everything -- the cap, the rotor, the wires, everything, the spark plugs. Then I had a brainstorm realizing that we are now on standard time. That's why it was apropos to mention that other thing. It starts to get dark at like 2:00 in the afternoon, and it happened to be getting damp and rainy. I told one of my guys, "stick the car outside. In a few minutes it will be dark and wet, and that's going to exacerbate the problem." Because if you have a bad spark plug wire or a cracked coil tower...

TOM: Aurora Borealis under there.

RAY: You are going to see a light show.

TOM: Yeah.

RAY: OK, you got it?

TOM: I got it.

RAY: So we put the car outside.

TOM: It gets dark.

RAY: It gets dark.

TOM: Start it up.

RAY: Rainy, lousy.

TOM: Raise the hood.

RAY: That's it.

TOM: Rev up the engine.

RAY: My guy goes out and starts it up and he says, "guess what, the noise is gone."

TOM: Whoo.

RAY: "How could this be?" I asked. He says, "I think I know the answer." I say, "you do? Give me a hint." And the hint he gives is "your brother's hair."

TOM: Well, I will tell you I have been struggling with this all week. I have no idea what the answer is.

RAY: You don't? Even with that hint?

TOM: I don't. Even with that hint.

RAY: Well, there was -- as I mentioned, as I failed to mention actually, all the hints are embedded right here. OK, and there was a discharge, an electric discharge, but it wasn't coming from the ignition system. The reason it got cured when the car -- instead of exacerbated when the car was put outside is that it was a static electricity charge.

TOM: I got that too, yeah. I got to that point.

RAY: And that's hence, your brother's hair.

TOM: Yeah, I got that.

RAY: Because when the weather is dry and balmy, Tom's -- Tommy's hair is wild and wooly. And it was coming from...

TOM: His polyester suit!

RAY: No.

TOM: No.

RAY: The fan belt. Most modern cars have a serpentile, flat type of grooved belt. Often times when the belt gets worn, as it is spinning around the pulleys...

TOM: It makes static electricity.

RAY: It makes static charge and zip, zip! It's especially common on newer cars that have, for example, plastic power steering pumps where there is no place for that charge to go and it builds up, it builds up, it builds up and it jumps from the crank shaft pulley to ground.

TOM: Wow.

RAY: To the engine block and you hear that zap and that's why it doesn't affect the engine performance. It's just annoying.

TOM: Yeah.

RAY: Pretty cute. A new belt fixed the problem.

TOM: But why did it go away outside?

RAY: Because with the high humidity you reduce the chances of static build-up. That's why you don't get a shock when you drag your feet across the carpet in the summer but you do in the winter.

TOM: And that's why my hair...

RAY: Looks the way -- well...I don't know.

TOM: Whoa, that's good! And you're going to ask me now do we have a winner, and I'm going to look on this page here -- ah, yes we have a winner. The winner is Jenny Latrell from Birmingham, Alabama. Congratulations and condolences Jenny since your correct answer was chosen at random among all the correct answers we received this week.
