While the vast majority of casino patrons are completely satisfied grinding away at the blackjack tables, a specific breed of gambler craves something much more extreme.

A proposition bet is an unofficial wager made strictly between two individuals, completely bypassing the casino, often involving highly bizarre or physically gruelling challenges.

Living in Total Darkness for Cash

In 2018, Alati bet a fellow gambler $100,000 that he could survive for 30 consecutive days locked inside a pitch-black, completely isolated bathroom.

Incredibly, after 20 grueling days in absolute darkness, the opposing bettor realized Alati was not breaking and negotiated an early buyout, paying Alati $62,400 to end the terrifying bet.

• Many prop bets center around rapid, extreme weight loss or unhealthy weight gain
• Golf course prop bets often involve massive sums wagered on a single, impossible putt
• These wagers prove that for some, the adrenaline of the risk is vastly more important than money

The Extreme Weight Loss (and Gain) Bets

In 2010, they incredibly bet Forrest $2 million that he could not drop from 225 pounds down to exactly 138 pounds within a few short months.

Conversely, brothers once bet each other massive sums that one could not eat $1,000 worth of McDonald’s food in a single, agonizing 24-hour period.

Brian Zembic’s Legendary Bet

Perhaps the absolute most ridiculous and permanently life-altering prop bet ever recorded belongs to a magician and high-stakes gambler named Brian Zembic.

Zembic, utterly fearless and lacking any shame, immediately found a cosmetic surgeon who agreed to perform the bizarre operation.

These unbelievable tales perfectly illustrate the extreme, almost incomprehensible psychology of the professional gambler.
