On Perry $OTC, I could swear that I saw - at least once - a player bottom out at zero. That player was then tossed for the rest of the game, and it was a two-person contest the rest of the way.
Thing is, am I really remembering that? I haven't seen any mention of that rule on Ye Olde Internets. I first found my "memory" called into question last summer, watching Aussie Temptation, when a 15-year-old contestant hit the goose egg, and kept playing on (and kept getting questions wrong, IIRC.) Am I perhaps just mixing up my memory of the actual show with the board game, which instructed players to sit out if they went below $10?
Anyone out there who's got a clearer rememberance on this than me, feel free.
