Plot.
An overconfident and guffawing spider (voiced by Cy Kendall) spots his intended prey, a mute fly, on the ceiling, and indulges in various cat-and-mouse schemes to try to catch him for food, including painting a load of buckshot with "Kandy Kolor" and luring the fly to eat it and drawing him closer with a magnet, which only succeeds in attracting a set of metal cutlery which the spider has to dodge to save himself. At one point, the fly manages to set fire to the spider's feet, and as the spider nose-dives like a plane, he exclaims "Look! I'm a Zero, I'm a Zero," referring to the Mitsubishi Zero in use by the Japanese during World War Two. He sees the fly on a wedding cake as a bride and dresses as the groom only to be blown up by a dynamite stick, left in blackface.
Eventually, the spider catches his prey, and, when he is about to carve him up while singing the song "Would You Like to Take a Walk?", the fly points to a wall calendar giving the day as "Meatless Tuesday", a reference to food rationing during World War II. The frustrated spider runs to the United States Capitol and rants to Congress "You can't do this to me! You just can't! You can't! You can't! You can't! You can't!"
