Rubber Duckie, a character on Sesame street, celebrates his birthday on January 13th according to a 1973 Sesame Street calendar. As a result, we celebrate the popular bath time toy on this day! Rubber duckies have probably been around since the early 1800s, but they were first patented in 1928 by Landon Smart Lawrence. You don't have to be a child to bathe with a rubber ducky. Celebrate this holiday by getting one for your bathtub!
