I always liked the GM cars which had the little AC vent centered under the steering wheel. We always called them (genitalia) coolers.
Now that's funny!
Remember the little swamp cooler units you could hang on the driver's side window, then roll the window up to lock them in place? They had a cloth medium that dipped into a water reservoir then incoming air from a forward facing horn blew across the cloth and put cooler air into the car. There was a string you pulled to rotate the cloth when it got dry. If you pulled too fast or hard on the string, it splashed water out of the unit onto the side of the driver's head. Sort of putting 'cool' into afterburner. Also good for startling Daddy.
