3 by the beer fridge, a church key attached by a rope to the cooler, about a dozen of those cheap ass punched aluminum miller lite can venting ones from a concert, one attached to the wine corkscrew and one on a waiters wine key, the one built into the can opener and cheap kitchen shears, about half a dozen keychain aluminum ones. And that is just off the top of my head. I know there are at least 6 more I have not listed, or are misplaced, or just have been forgotten about. Then again, pretty much anything can be a bottle opener if you are thirsty enough. I have used a sheet of paper before to great effect.
