The Show-Off (1946)

Lowly clerk Aubrey Piper has a fondness for exaggerating about himself to impress people. His fantastic tales of visiting China and working as a manager at his place of employment charm his blind date, quiet and lovely Amy Fisher. His false bragging and nearly burning down the Fisher home gets him in bad standing with Amy's family. But Amy is smitten and gladly accepts Aubrey's marriage proposal. Soon, Aubrey's spendthrift ways and show-off manners soon land the couple in financial and legal hot water.
