Whose Baby? 1929
In this one, an episode in the Universal Studios series called “Horace in Hollywood”, Lake dates up Gertrude Messinger. While waiting for her outside a movie theater, he is handed a baby by its mother with a request to mind it while she goes offscreen. Naturally, Gertrude thinks the baby is Lake’s. So does Glen Cavender, who seems to be in about forty percent of all short comedies in this period, as a beat cop.
