Amongst the jokers, no one else fears punishments as much as Sal does. Looking back through the show’s history we can get a plausible explanation for this behaviour: Sal was rather unprepared for the challenges so much so that he ended up suffering through 3 consecutive punishments during the start of the first season.
That of course left an indelible mark on the guy but for good reasons it would seem as he ended up pulling himself by the bootstraps to bequeath that dismal legacy to Murr.
Nevertheless, the “trauma” lingered on and the jokers being the heartless bastards we love the for have callously exploited this fear in the way of surprise punishments that always find Sal flat-footed – literally it would seem.
