My habit of daydreaming took me back to my youth and some of the practical jokes we used to play. In those days young kids drove older cars from the 30s and 40s like maybe a Model A w/rumble seat or a '39 Dodge,etc. Most of those cars had hoods that could be opened from outside the car. We'd spot some young guy going into the movie theatre with his girl friend and then find his car and, after the engine had cooled down, place about a half pound of limberger cheese on the intake manifold. It was a given that the guy would come out of the theatre with his girl and then drive out to some lonely country road and park for a while. While driving the intake maniflod stayed fairly cool, but after setting for a while it would get pretty warm and the smell of the limberger would waft into the passenger compartment. Kind of like the smell of a rat that had been dead for a while. Another "under the hood" trick was to get a whistle bomb from the pool hall, where they were a hot seller, and hook one end to an exposed spark plug and the other to a ground. Made a loud whistle followed by a big bang and a cloud of smoke. We got one guy maybe 4 or 5 times in one week that way. Yet another was to get under the hood of a Ford V8 and pull every other plug wire. The engine would run but very feebly. Would only crawl down the street. This all in addition to the usual greased steering wheels, fahrt cushions, etc. All in the name of good fun.
