We had a gaming party at work on a Friday afternoon, and I happened to have recorded my games. Reviewing it, I found I did play against her (and 2 others) in a free-for all. But it was clear she just fabricated the events. Funnily enough while I was playing her, I didn't even know it was her (it was a woman I barely knew and only had spoken to a couple of times).

Anyway, presented with the actual recording she dropped the entire thing and yet managed to have absolutely zero personal or professional repercussions.
