While driving around lately, you might have noticed that some cars have a rubber duck on their dashboard ... they learned that the bath toys are part of a movement among Jeep owners.

Jeep owners 'duck' strangers' cars, mysteriously leaving the toy on the vehicle's windshield or side mirrors. The same tradition goes for vacationers on cruises, who hide rubber ducks for each ...

Still, it wasn’t until Georgian-Russian-American sculptor Peter Ganine patented his design in 1949 that the rubber duck became as famous as we know it, selling more than 50 million toys worldwide.
