*How's this for the premise of a race? Each car entered in the race must carry a pineapple, and if by some misfortune the driver reaches the finish line without the pineapple in the car, then he/she is disqualified from the race. That may sound simple, but a band of jewel thieves has smuggled a diamond in one of the pineapples, and they mean to get it back, (only they're not sure which one it's in). *Source: Back of Card
