Harold -- in the person of Lonesome Luke -- and Snub Pollard go into the park and try to pick up women. Their boyfriends object violently, so the would-be Lotharios dream of stone-age society, where in order to pick up women, all you needed was to hit their boyfriends on the heads with clubs. They wake and put the plan into action, with poor results.
That's almost all there is in this alleged comedy: hitting people on the head with large clubs, with police sticks and with the occasional coconut -- which breaks the coconuts. This goes on for 25 minutes and it is beyond too much.
Harold Lloyd felt so too. He dropped the Lonesome Luke character and developed his now famous "Glasses" character. Looking at this example of the former, it wasn't a moment too soon.
