6x15 - Laverne & Shirley

Disappointed after not receiving the customary tri-monthly $5.00 raise, Laverne and Shirley write a nasty letter to their boss. At the end of the day, it is revealed that they DID get a raise, after all, but also that the nasty letter is sitting, unopened, on the boss's desk - waiting to be read the next morning. Desperate to save their jobs, Laverne and Shirley go home and try to hatch a plan to get that letter back, before morning.
