Go ahead, bet away your April month's rent on tomorrow's The Ultimate Fighter Live fight. I'm sure if you explain it to your landlord, he/she will understand. Don't worry, it's happened to me before. I ended up pawning my bass guitar only to use the money to bet on another fight. Fortunately I won, which enabled me to barely not get evicted from my apartment. Keep in mind, this was a different time in MMA. Back when people truly thought Affliction: Banned could be the 'game changer' in mixed martial arts. We've all seen that promotion dissolve in a effigy of sheer WTFness, now you can drop bets on TUF 15's live bout of Cristiano Marcello vs. Justin Lawrence and potentially see your bank account disintegrate as well.
Check out these odds from Bookmaker, and notice the $500 limit. Apparently that's their method of preventing you from becoming a totally degenerate gambler.
