When you've lost your rag...

Not looking for anything heavy here, just stories you can look back on and laugh at yourself!   I am a bit highly strung myself, but I can't imagine I'm the only one to lose patience with something I'm trying to do....

Awkward coax connector and poor quality solder?
Antenna which just won't tune in no matter what you do?
Fiddly microphone connectors?   

I know someone who had problems with an antenna and stuck a grinder though it to "teach it a lesson" 

Are there any particular aspects of radio which is frustrating to you?    I get really agitated doing mic connectors.   Many fiddly pins close together, plastic which melts easily and outer insulation which is nigh impossible to cut through without chopping into the wires inside!   And I mustn't forget, tiny fiddly screws capable of disappearing into thin air.    Or are you one of those who enters a positive zen like state when working on your equipment.

Maybe something non-radio related.   Car job gone wrong?  Something useless you've bought online?

I once lost the plot trying to change piston seals on my car brake callipers, couldn't get piston to go in with the new seals in place, so in frustration, lobbed the piston straight through the (unopened) garage window.      Stupid thing to do, I know.   That was when I was a bit younger... I like to think that now I've mellowed a bit and I'm more likely to walk away from things and come back with a calm fresh mind!
