I got
ZANGED but good once, I was on my way out feed my beasties.
This was about 25 -or so years ago.
We had those gate spring tensioners disconnects one low and one at about 6 feet.
I could disconnect the low one and open the gate and walk under...or so I thought !
Bent down and took the lower off, stood up opened the gate, and bald spotted the upper one....
ZANG 
bit my tongue, reared back and bald spotted it again

I coined many a NEW colorful exclamation that morning, especially since my wife thought it was hysterical !

Moral, wear a fricking HAT
