Tied for the absolute worst bet in the casino is a bet called "Any Seven," with true odds of 5-1 but an actual payoff of 4-1, giving the house a whopping 16.67% vigorish! (As you can see from the accompanying craps layout, the casinos have a penchant for drawing the players' attention to sucker bets by printing them in red letters against a green-felt background -- I mention this because if you should ever find yourslef at a craps table and get suckered in, the very least you should know is that red means STOP!!!)
Anyway, when the whack jobs who choose to play the "Any Seven" call out their bet to the stickman, rather than shout out the dreaded "S" word, they call for a bet on "Big Red" instead.
