Many years ago, our party found itself on a boat going down a river. With nothing better to do, we started fishing, hoping for the plot to continue after a couple of inconsequential dice rolls.

It didn't. We literally spent hours irl rolling dice to fish because our DM was very clearly not interested in running an actual game that day.

We soon started playing without him, bit I think that is the closest I ever got to OSR the ttrpg.
