I am gonna pitch the biggest fit

We had a baby throwing a hissy fit here in the library.
I was busy tuning it out until I realised just how cathartic it must be for that child to just express himself so well by crying and temper tantruming (not that I am condoning that kind of behaviour on a regular basis - but when there has been a viable injustice than I think that kind of behaviour is acceptable).
Which got me to thinking that I wonder why it is that adults don't get to do that kind of hissy fits? I am aware that some adults do it on a regular basis, in fact it probably never ended from childhood, but there are some adults who could probably really use the good stress release that a big hissy fit would give them.
You know?
Just a really good chance to lay the smack down, scream about something, cry, express yourself and then let it out and be much much better.
I wish I could do that.
