Jimmy got into trouble about something or other from other adult scout leaders. When they scolded him, he decided it was all because my dad didn't like him. So he ran up on my dad, sobbing, carrying a huge rock (maybe 2X as big as his head), trying to brain him. My dad heard him coming (because of the sobbing) and dodged and rolled him to the ground.
The most disturbing part was how, after Jimmy had been thrown out of camp for losing his shit, his dad insisted on coming back the next day to act as counselor again, insisting nothing was wrong.
At first I thought this was a Jimmy Winchell story.
