Yes, We Have No Bananas (or Anything Else for That Matter) Dharma & Greg : Season 2 Episode 10

A gently surreal episode whose humor derives from escalating skewed logic in the Preston Sturges mode: Greg's hostile secretary Marlene (at last the wonderful Yeardley Smith returns!) is offended by her annual staff evaluation as ""Satisfactory,"" while Greg is overjoyed by his ""Superior"" rating until he learns Pete got the same rating. When Greg confronts his boss, he is driven to desperation by the man's apparent complete inability to discriminate between similar items (Tahiti vs. Buffalo as a honeymoon destination, freshly baked bread vs. moldy supermarket bread), and almost unhinged by the boss's decision to put Pete in charge while he is in medical leave. At the same time Greg must deal with Dharma's impulse decision to open a store without first deciding what she will sell, and the fact that the place quickly becomes packed with people who find Dharma's environment strangely soothing and establish a barter economy amongst themselves. There is of course only one ""logical"" conclusion
