Tramp, Tramp, Tramp!.

Jackie Gleason and Jack Durant are teamed for the first and only time as Hank and Jed, a pair of dimwitted barbers who are forced into bankruptcy because all their customers have marched off to war. Figuring that if you can't beat 'em, join 'em, Hank and Jed try to join the Army themselves, only to be rejected for a variety of reasons (When asked to read the eye-chart, Hank says he can't-not because he can't see, but because he can't read).
