Happy birthday, rubber ducky! The rubber ducky is celebrated on Jan. 13, which reflects the birthday of “Sesame Street” character Ernie’s squeaky bathtime friend. The original “Rubber Duckie” song has been viewed more than 24 million times on YouTube. “Sesame Street” marked the occasion with a new twist on the classic song, performed by “Hamilton” star Daveed Diggs.

According to the National Day Calendar, the rubber ducky “has come a long way from his first concept as a chew toy for children.” Given that rubber was a valuable commodity during World War I and World War II, rubber duckies started to get made with vinyl and plastic. One of the earliest patents for the rubber ducky came in 1928 with a hollow rubber toy in the shape of a duck. The weighted bathtime ducky was meant to stay afloat when rocked.

National Rubber Ducky Day was celebrated Friday on social media. Take a look at some of the tweets below:
