There are vast differences between being silly, foolish and stupid, don't you think? Off the top of my head, I'd say that
silly is splashing around in puddles in the rain,
foolish is putting on a bathing suit and jumping in an outdoor, unheated pool during extremely cold temperatures,
stupid is driving your truck on a frozen body of water as part of an ice fishing plan without first checking the thickness of the ice.
The last is the kind of thing that winds up on TV shows.
