Don't say hacked
I was a volunteer at the library, and they complained one of their printers wasn't printing. They had called support and it would be some time before the tech arrived from downtown. I walked over to the printer, went through the menu, and saw the IP address was blank. So I typed in the IP address from the label on the front of the printer, and it sprang to life. Let's not ponder the cost of an onsite visit for such a fix. They asked me how I fixed it, and I jokingly said "I hacked it in". I had to go to a meeting, at which they read me the riot act and told me I couldn't be a volunteer any more. The shame! Fired as a volunteer!
Now I use the word MacGuyver. Everybody loves MacGuyver! Doubles as a verb, too. MacGuyver's hacks were carefully designed to not do anything, in case kids were tempted to try them at home. But I don't think librarians can figure that part out, so MacGuyver is good.
