In all seriousness, though, the amount of money in the pot does matter. Let's take a 5-10 game, where two other players were in until the guy caught his open trips on sixth. Now they both fold to his bet. Let's assume there was one bet on every street -- there would now be $80+ in the pot. So you're getting 8-1 on your call here. You won't call the river if you miss your flush (since you can't beat his board). You will call if you hit. So in that case you'd be getting 9-2. If this player has not been aggressive so far and could have started with a draw, then I think a call would be in order. If he has been leading the betting the whole way, you might fold. It's certainly not a good situation for you, but there are some times in stud where you have to just grit your teeth and call a bet or even two on the end just because the pot is so big.
