This fits the thread (I think!) even though it's not really a typo....

Years ago I worked on a Computer Helpdesk and users of the computer all had UIC's (User Identification Code). They were grouped by department so if you changed departments your UIC would need to change as well. One day I received a phone call from a woman who asked if I could change her IUD. I put her on hold, for the purposes of laughing my ass off, and when I returned she had realized what she said and was laughing harder than I was!!!

OK, so maybe it didn't really fit the thread but to be honest, what thread WOULD that story fit into?!?!?!
