Based on the Happy Hooligan comic strip, by Frederick Burr Opper. Happy speaks with someone in the park and takes a trip to the moon on a rocket that looks like the front half of a current racing car, where he is made king of the moon. A ballerina does a shimmy and Our Hero winds up back in the park being accosted by a cop. The inference is that he has fallen asleep and dreamed the entire trip.
