4 parts Gin (Tanqueray)
1 part Vodka (Stoli)
Fill with Beer
Find a large shot glass (1 1/2 - 2 oz. is appropriate). Fill 80% of the way with Tanqueray gin. Fill another 15% with Stoli or Absolut vodka. Fill to the rim with cheap "Ice" beer (best results w/Busch Ice).
Invented at my cabin the day after a huge party using the only stuff left over. I used Tanqueray gin, Stolichnaya vodka, and Busch Ice beer. Hope you don't try too many!
