In one of the episodes that recently aired we have Kramer waiting at the airport to meet Jerry's girlfriend because Jerry is delayed getting back on a flight from Ithaca. Kramer starts making bets with a Texan in the waiting area on the flight arrivals and goes in debt $3200. Kramer gets Newman to back him with collateral for one more bet. Kramer makes one more bet, for double or nothing, and wins. We see the Texan signing a bunch of traveler's checks and paying them to Kramer (they're later torn up by the Texan, but that's not important).
So if Kramer owed the Texan $3200 and made a "double or nothing" bet and LOST, then he would owe the Texan $6400, right (double $3200)? But if Kramer WON the bet, he would owe the Texan nothing, right? So why is the Texan paying Kramer anything? If the Texan is owed $3200, and a double or nothing bet is made, then either the Texan will get $6400 or $0 - but in no case should the Texan be losing any money!
Have I missed something, or did the writers?
