I've only seen the Maryland one once, and that was exactly the reaction I had to it.

I've reached the stage where I 'tune-out' every time the cheese string thing comes on, but had at one point sat there thinking that it obviously wasn't a human or animal, so the easiest solution to the threat to international air travel posed by a glass of milk within processed cheese was a controlled explosion, like any other suspicious package.

I like the idea of the car, but how would you explain to the insurance company that you accidentally left it in the loo/restaurant/cinema and it wasn't there when you went back for it? The one where you can pull off the top layer of your kitchen (and now your bathroom too, I notice) complete with all the grime would be of far more interest to me at the moment
