Mac and the Waitress plan to sneak into Charlie and Frank's apartment to have sex there (to rub it in Charlie's face); they are discovered hiding in the bed.

The Waitress confesses she poisoned pies and also 'diarrhea-poisoned' Frank to silence him after he learned about the cherry scheme; she also admits poisoning other items to protect her operation.

The episode depicts a coordinated scheme: bribery of a health official, rounding up/hoarding cherries, using contamination to force disposals, reselling cherries, and using threats — with multiple characters (Frank, The Waitress, Cricket, Mac, Dennis) participating in different roles of the same illegal enterprise.
