When the one donkey and rider run out of the ball park, they go out into Culver City and stop along the sidewalk in
front of the Bank of Italy (which became the Bank of America). This is the same place that several scenes in Charley Chase's classic Limousine Love (1928) were shot.
Though Pete Smith appears with donkeys and pretty chorines in several publicity stills for this short, there are no girls in the film, nor does Smith appear in, or even narrate, this one.
This was a real exhibition sport in the 1930s and beyond. Some entrepreneurs set up travelling "trained" groups of donkeys that civic and other organizations could hire for fund-raising events. Later in the century came the similar donkey basketball games.
