Children's playgrounds are made for children. For good reason.
Climbing frames are generally built for fun and enjoyment by those same said children.
If you're an adult,
With several other drunk adults egging you on,
And stupid enough to try to play on said climbing frame,
In pitch black,
You're likely to come off second best.
Once you're sober, your broken humerus will serve as a good reminder.
Yup. That's the one they call the funny bone.
I wonder why?
