Will Milton fall for any of Marvin's April Fool ruses? Not, says dour Milton, for the same ""dumb jokes"" as the year before. Marvin defends himself--""jokes are supposed to be silly""--and then Modell presents him with some nifty sight-gags (two trees shaped like ""big green chickens,"" ""bows and arrows"" in the form of signs, ""a big giant"" of a man,"") that Milton is smugly contemptuous of as well. Then the two turn to each other with the oldest gag of all--""Hey, Milton, your shoelace is untied""; ""Yours is too, Marvin""--and, by golly, the shoelaces of both (April Fool!) have come undone. With a pair of personable comics like Marvin and Milton, one clever notion can carry any holiday of the year.
