Fixed with tape
What have you fixed with sticky tape?
Not IT related, but when I worked at a radio station, one year management decided that we all deserved a night off, and so they would organise the Christmas bash by hiring in everything - in the past we'd supplied our own PA gear and often on-air talent would do DJ duties.
Everyone gathered at the local golf club, only to find that the hired-in DJ had non-working kit, so muggins 'ere, the "station engineer", was asked to investigate (so much for an evening off). The only tool at my disposal was a Victorinox (I've carried a basic one since I was about 15).
Long story short, the problem turned out to be a dodgy audio lead between the mixer and the amplifier but of course while our portable kit came complete with a selection of spare cables, the cheap DJ had nothing. And we were miles away from base so it was a bit pointless to nip back to the office for a spare cable, or even a soldering iron.
Ended up fixing it with the foil from a packet of fags(*) and some good old-fashioned Sellotape that the barman happened to have. Lasted all evening :-)
(*)Said fags happened to belong to our only vaguely famous on-air talent, a bloke known as Bobby McVay
