Angier,

My favorite Tow Bar story came from working the First Flagman Position at a Golden West EAA Regional Fly-In.   A 172 landed, turned off the active with the Tow Bar attached and bumping along the taxiway, (apparently it rested on the nose wheel fairing in flight).  I signaled him to stop and after multiple cut engine signals with me blocking him he finally shut down, then he got out ready to do battle.  When he saw the Tow Bar, astonished would not quite be the word.  His wife was with him.
