When I was TDY in Biloxi I played black jack with a friend at the casinos. I had no luck myself, but I could hold my drinks better. So we developed a system. As he got more drunk while playing I'd tell him when to hit or when to fold.

If I'd been playing I would have never gotten the cards we needed, but with me keeping him "sober" we managed to clear 1,800 bucks or so across the 3 month TDY.

So on our last weekend in Biloxi we took two other friends and drove down to New Orleans where we blew it all in a weekend of stupidity. It was awesome.
