Once had a user manually change their ticket to Priority 1, which we used to indicate dozens of people/everyone down, because their M key only worked half the time they pressed it.
I once got an emergency after-hours ticket to fix a computer that was shutting off randomly. I went to check it out, and the power plug was loose. I asked the user about it, and she said she knew it was loose, but she couldn't plug it in because her skirt was too short. No, this isn't an intro to a porno.
