I can gladly say I have yet to do so... in fact, I'm 1 for 1 on those.
See, I made a Pinkie Promise to somepony in a pony chat room that if I got the piece of loot I was searching for(the Borderlands 2 Infinity pistol) while listening to a brony musician called Forest Rain, then I would take on the name of Horsetradamus for the entirety of my stay there. Well, it seems the universe wanted that to happen, and I got my pistol during Forest Rain's cover of Memory Lane, made by another brony musician. Long story short, I held true to my Pinkie Promise.
