It's a Great Life (1954)

Two ex G.I.s, Denny and Steve, return home and take a room at the boarding-house of doting Amy Morgan. Also in the house are young, beautiful Cathy, and Amy's irascible, penny-pinching chiseler brother Earl. The series follows the exploits of "the boys" as they try to get rich quickly and meet the girls of their dreams while working as vacuum-cleaner salesmen.
