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.
The Bathroom Isolation Bet
One of the most famous and psychologically terrifying prop bets in poker history involved the wealthy professional player Rich Alati.

Alati was placed in the dark bathroom with only a bed, a bathtub, and regular deliveries of completely unseasoned, random food.

The most famous example involves poker legends Phil Ivey and Tom Dwan, and the notoriously overweight gambler Ted Forrest.

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.

Furthermore, the bet stipulated that Zembic had to maintain the implants for one full, complete year to collect the massive payout.

In a bizarre twist, he earned a massive $10,000 annual residual payout from the original bettor for every additional year he kept the implants.
