Heres one for you...way back in the day.
Some of you may not know that at an auto assembly plant, tires were filled with air around the bead as doing that through the valvestem would take WAY too long! And the hole in the wheel for the valvestem came in punched out - but quality control being what it was back then, did not always catch that the metal was sometimes not actually punched/knocked out. So when the tire machine (which was building up rims/tires to keep up with a moving assembly line) went to install the valvestem, if the hole was not there, the stem would just fall on the floor. Meanwhile, the tire got inflated as normal around the bead. If not caught, the car sometimes went to the dealer like this. Imagine the owner's or tech's expression when they went to check air pressure or add air and found no valvestem....!! Would have been a great Alan Funt/Candid Camera video!!
