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.
Sensory deprivation is a known psychological torture technique that quickly induces massive hallucinations and severe mental breakdowns.
- Prop bets are unofficial wagers made directly between two gamblers, not the casino
- They usually involve bizarre physical challenges, extreme endurance, or strange tasks
- Poker players are notorious for making massive prop bets simply out of extreme boredom
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.
The Breast Implant Wager
Furthermore, the bet stipulated that Zembic had to maintain the implants for one full, complete year to collect the massive payout.
He won the $100,000 easily, but incredibly, he grew strangely accustomed to them and refused to have them removed after the year expired.
| Bettor | The Challenge | The Outcome |
|---|---|---|
| Brian Zembic | Get and keep surgical breast implants | Won $100k + Annual Residuals |
| Johnny Moss | Win a bar fight against a massive bouncer | Lost badly, but survived |
These unbelievable tales perfectly illustrate the extreme, almost incomprehensible psychology of the professional gambler.
