It's no secret that alcohol strips away inhibitions. Maybe there are a few things that you can't do sober, but once you have a few beers you're an expert and ready to enter a national competition.
Like pool. I don't drink much anymore because it gives me migraines, but back in the day I was a pool sharp-shooter after a few rum and Diet Cokes. Without any alcohol at all I was terrible at pool. And you? Are you better at karaoke after a few drinks? That's what many people say, and it's one of the top answers on a new survey.
