A friend of mine was on the road with a four-piece band once. Having had some awesome "chili wheels" at a truck stop, he was needing to use the restroom urgently an hour or so later.
Their van pulled into a gas station, he bolted inside asking for the restroom key (the kind bolted to a piece of broomstick), and was told it was never returned by the last guy who took it.
The attendant said, "They just left, it was Willie Nelson's bus driver!"
That was my buddy's brush with fame and immortality.
