in a casino ($2-$4), two regulars, who soft played each other blatantly when they got heads up had two hands with quads over quads. They each won one of the two pots. Both pots were tiny, because they wouldn't bet against each other. One guy actually said he wouldn't bet when the turn made a second pair on the board because he knew he must be beat, and he was. At the Trop in AC. I had no idea at the time how rare that was.
