Fish-loving college graduate Allan Lane (as Bill Norman) agrees to become a lowly milkman for 30 days, so his millionaire father will believe him worthy of a proposed six-month tropical expedition, aboard the family yacht. So, Mr. Lane begins enthusiastically delivering "Arlen Milk". On his route, he meets pretty débutante Joan Fontaine (as Sheila Harrison), whom he mistakes for her family's maid. Ms. Fontaine's family has fallen on hard times; and, they want her to marry wealthy stuffed-shirt William Brisbane (as Wally Martin). But, Fontaine would rather hook up with Lane the "milkman"; and, he has fallen in love with Fontaine the "maid".
Lane, the future voice of "Mr. Ed", and Fontaine make a charming pair of 1930s "screwball comedy" "milkmen". There are a few cute moments, and the film's supporting cast is strong. Cecil Kellaway (as Geoffrey) and Hilda Vaughn (as Mary) are, of course, excellent, as the actual pair's servants. Mr. Brisbane has a great part; and, he gets to sing. The story is mostly fair, with a few good moments. Fontaine's milk truck attack on the runaway couple's pursuers shouldn't be missed. The ending "double take" of kisses ends the film on a sweet note.
