Did you have one of these as a kid? Do you still have one?
The rubber duck is now in the National Toy Hall of Fame, joining the ancient game of chess, which also made the 2013 class.
The pair beat out 10 other finalists that included bubbles, the board game Clue, Fisher-Price Little People, little green Army men, the Magic 8 Ball, My Little Pony, Nerf toys, the Pac-Man video game, Teenage Mutant Ninja Turtles and the scooter.
Online polls had Teenage Mutant Ninja Turtles and My Little Pony running strong, but in the end a national selection committee made up of 23 experts voted in the winners.
A statement said: "The two inductees are fantastic examples of the two extremes in the world of play. One is so strategic. It's rule-driven. It's something that adults play and puzzle over and at the other extreme is a toy that's pure fun. It has no rules. No one wins or loses. You squeeze it. You float it. It's so silly, so fun."
Chess can be traced back centuries to an ancient Indian war game, but evolved into the game it is today by 1475. The rubber duck has been a fixture in pop culture for decades. Rubber toys first appeared in the late 1880s, but no one knows exactly who created the idea of the rubber duck.
