Betting on both teams (also called arbitrage betting or middling) can result in the bettor making a profit  regardless of the outcome  by placing one bet per each outcome (and with different betting companies). Again, the conditions must allow it.

Bettors are far less likely to win parlay bets than individual bets, and sportsbooks make more money from parlay bets than individual bets. The odds on individual bets are calculated even to generate a small profit for the sportsbook. That gives gamblers a 50% chance of making a profit with standard bets.

This is the first time the Impala is seen with Ohio license plates instead of Kansas plates. Sam explains this was done due to their fugitive status.

It bears a Sedgwick County, Kansas license (though their hometown of Lawrence, Kansas is actually in Douglas County) plate KAZ 2Y5, a reference to Kansas, the Winchesters' home state, and 2005, the year the show premiered. Starting in What Is And What Should Never Be, the car sports a new Ohio license plate (CNK 80Q3).
