not proud, but impressed

So who here has done things of which they may not be proud of, but impressed they did? I'll start. A few years back I turned someone from a full blown, super religious Catholic into an atheist in 15 minutes of conversation. First words I heard from their mouth before we talked was "god will always bring salvation." And the last thing after our conversation was "There is no god, everyone is wrong." While this may not have been the best action I have taken, and do feel sorry for the guy now. I'm impressed I was able to do it. Anyone else have such stories to share?

isn't this like tellng them to go into the dark side, knowing full well that the dark side doesn't really have free pizza
