True story that I recalled while reading the Jack stand thread.
When I was young my grandaddy would honk at every NAPA truck until they stopped and lowered their window. He would yell, "SIR! YOU LEFT YOUR HAT ON TOP OF YOUR TRUCK!", and drive away laughing his butt off.
As a kid, the variety of profane responses he would receive were hilarious. Every so often, one would try to catch up to give him a piece of their mind, but those 4-Cylinder trucks were no match for his Impalas.
To me, that's what always made the elders so cool. They misbehaved worse than us kids did, and always got away with it somehow.
