Well it happened this morning, and it was bright orange paint not blue like in this picture.
We had just made our turn into the hospital drive and had to stop in the middle of the road, jump out of the SUV and go frantically searching for that spray paint can. It took us a while to find it with all of Rick's tools in the back, but thankfully it was lodged under one of the back seats spraying out most of its contents. One of the plastic floor mats got destroyed, or you might say that it is now a colorful fluorescent orange to match the underside of the back seat and part of the front drivers seat. It could have been worse. It could have sprayed the whole interior ceiling of my nice Saturn along with us, but it didn't.
Since we only started hearing the loud hissing noise after we made our turn into the hospital drive, I surmised that the can must have rolled down under the seat, hit the spray button and gone off.
I laughed about it all the way home later, but Rick wasn't able to laugh about it......or at least not yet. Accidents happen and at least nobody was hurt.
