Dan Rice was a circus clown...or rathe a circus leader...in the mid 1800s. It is because of him that we have terms like "Jump on the bandwagon". He essentially made fun of politicians...before that was cool!
He also is the reason that we have the iconic "Uncle Sam" Army recruiting posters...those drawings were modeled after what he used to wear during his circus act. Learning about Dan Rice while living not far from where he made his home...was so much more than we expected!
