........... was. Ringling Brothers and Barnum & Bailey Circus. 6'3" clown curled into a gasoline-powered car (hard top) no bigger than a dining room chair.
Saw his act several times when I was a kid - we used to ride the streetcar over to NE New York Avenue and "help" set up the circus by hauling water to elephants and other animals as well as spreading sawdust on the Midway path. We got free Big Top tickets in exchange.
