Putting honey on the hand of a three-year-old for a photo op with a wild bear is perhaps the best example of stupidity I’ve ever heard.  My wife’s step brother and friend saw this happen. Fortunately, they could scare away the bear by making a lot of noise. Then mother looked at them and said., “You ruined my picture!” People get ideas about something and don’t think through the potential consequences. 

Stupidity is not the opposite of smart. It is behaving without common sense or judgement....
