It would be funnier if the characters doing the punching weren't doing it over such idiotic reasons. He falls and accidentally splashes her, having no idea that she was there. Should not have resulted in a punch. He falls and scrambles to regain his balance and grabs her breasts in the process, then gets punched for his troubles. Comedy gold.
