Brian Zembic is a professional gambler who has had his fair share of bad luck. He has made a name for himself by participating in elaborate bets. In the past he had agreed to live in a bathroom for a week for $14,000, and he lived in a box for a week for $25,000. However, his biggest claim to fame is when he agreed to live with breast implants for $100,000. He did what he would later call his "most stupid" bet out of desperation in 1996 after losing over $100,000 from a bad stock tip.
The breast implants themselves cost $4500. Zembic was able to get the procedure done for free after beating a cosmetic surgeon at backgammon. The original bet was based on an argument he had with another gambler who, after opining that getting breast implants was a crazy thing for women to do, bet Zembic $100,000 that he couldn't have breast implants for over a year. Zembic took him up on the offer, received the $100,000 in 1997, and as of 2006, still has breast implants.
