I am taking my youngest brother to Vegas for his first time ever when he turns 21 later this month. I am trying to think of a drinking game we can play while walking around the strip, both inside and outside the casinos. I am having trouble thinking of things to include in the game. Basically I am looking for: "If you see X, then drink Y. One thing that comes to mind is every time a porn slapper hands you a card, take a sip. If you hear someone cheer at a slot machine, take a sip. If you get propositioned by a hooker, finish your drink. Any suggestions for more rules?
