I have seen people plug a VGA cable in the wrong way round.
I'm embarrassed to admit I managed that, on my first PC. As it was my own personal computer, and it had cost me a lot of money, I spend a long time carefully straightening the pins with needle-nosed pliers. Plugged it back in, kept my fingers crossed - and it worked! I screwed it in firmly and never unplugged it again.
(Well, I suppose I must have done eventually, as I no longer have it...)
