If you find it tough to take bobbleheads seriously, you’re not alone. But perhaps you should. And National Bobblehead Day on January 7 now is a chance to recognize the fun behind these dolls—and admit you like them without feeling self-conscious about it. Although these goofy dolls have become popular in the past couple of decades, bobbleheads have been around for the last few centuries. We bet you there’s a bobblehead version of any famous person you can think of: presidents, sports figures, Supreme Court justices, and the Beatles all have their own bobbleheads.
