no horseplay

I worked today in the ICU. In June the ICU moved into a beautiful new unit. It is honestly spectacular. The old unit is now being renovated into a swanky new cardiac surgery ICU. Outside the construction area is a list of rules. Rule #5 is "Absolutely no horseplay allowed." I found myself standing in front of the large list of rules laughing to myself.

First, why does this need to be on the list of rules? why on earth would men, or women for that matter, using dangerous power tools, like nail guns, actually engage in horseplay? and how is horseplay actually defined? so here's what Mr. Webster says, "rough or boisterous play or pranks." come to think of it horseplaying with a nail gun might actually be fun.

Second, why does horseplay need to be banned? From my experience with some pretty serious stuff a little horseplay might do us all some good....but perhaps not with a nail gun!
