This thread reminds of something that happened a long time ago when I was living in Arizona.
A truck moving a manufactured home miscalculated the needed height to go under an overpass. The top of the home hit the overpass bridge, stopping the truck and blocked traffic. Police and engineers were there trying to figure out how to get the thing 'unwedge' from the bridge. After a couple of hours of traffic being backed up and engineers/police pondering the situation, a car drives by and a young girl yells out the window, "let the air out of the trucks tires!'.
Sure enough, letting the air out of the tires dropped the home just enough for it to unwedge from the bridge, and the truck and trailer/home passed safely underneath the overpass.
I have used that same tool. I just now saw the thread, or would have spoken earlier. It works great for pulling staples, although, I grinded the tip down a little, so it could slip under the staples better.
