Car Farts

So, we were driving to northern Michigan for our family vacation Wednesday with four kids in the car. We are coming up on a construction zone around Flint, MI where they have about 6-8 of those bright orange cables stretched across the expressway (like the rumble strips on the side of some roads) that make a noise when you drive over them. We drive over them not thinking anything of it until we hear:

"Did the car just fart?"

That came from my eight year old son who we thought was lost in his dvd movie he'd been watching. He had no idea that we had drove over anything. He just thought the car had gas:)
