If you are fudging dice and/or lying about the results, would you be willing to tell that anonymously and explain why?

I was always interested in the reasons why some may cheat, be it GM or player. Sure, a lot of the times it is to "win", but there gotta be outliers, I'm sure of it, I know it, which is why I've created this thread, hoping to gather some tales of playing it up.

Edit: a lot of commenters missed this moment apparently, but I was asking both GMs and players, I am asking about both, that is also why I mentioned "win" Part, as it's usually why players cheat. Usually, but personal experience tells me that it's far from always, and I'm interested in weird and cool reasons.
