Just last night I was just watching a Mack Sennett film called “Fatty and Mabel at the San Diego Exposition” starring Fatty Arbuckle and Mabel Normand (who else?) that featured one of these. TCM has been showing these Sennett films every Thursday night, and I had recorded this one a couple weeks ago.
