Synopsis by Hal Erickson
While trying to take an afternoon nap, Popeye is pestered by a pack of pesky houseflies. Using "pipe power",he manages to shoo most of the insect away, but one particularly persistent fly remains behind. Fed up with the fly's pranks, Popeye knocks his little nemesis into the kitchen--and directly into an open can of spinach. Galvanized by the green vegetable, the flight embarks upon a major assault against Popeye, leading to chaos, destruction. . .and a square dance? Flies Ain't Human was remade in color in 1949 as The Fly's Last Flight.
