Beer Bottle Lawn Darts

I was reading about the champagne lawn darts (linked). I like it, but one throw per bottle means you have to drink too much champagne to have your game.

Beer bottle darts are corks to be jammed into ithe empty beer bottle. There is a spike protruding up from the cork and a collar to keep the whole thing from being forced all the way into the bottle. After drinking your beer, insert the dart cork and hurl away!
