This made me remember - when I was younger, I fucked around with my friends a couple times with this trick. If we stopped to put air in the tires, I'd offer to hold the valve cap. Stick a tiny pebble into it and hand it back. Watch the confusion as they think there's a valve stem leak every time they tried screwing the cap back on.
Especially when you consider the noise and the time it takes to manually let air out. Pulling the pin with needlenose pliers would be the way.

That's hilarious
