Phoebe and Rachel scheme to make Monica and Chandler admit their relationship.





























































































































This scene flips the episode's information hierarchy: once Monica and Chandler learn that Rachel and Phoebe are pranking them, they keep the secret alive to turn the prank back on the pranksters.













Monica establishes the third layer of information asymmetry: Rachel and Phoebe know about the relationship, Monica and Chandler know that they know, and neither side will admit it.

Chandler coins the thesis statement of the episode's second half as the hunters become the hunted.
The pinnacle of sitcom dramatic irony: Chandler's fake seduction call backfires because Rachel immediately deduces that Joey leaked their prank, creating a four-deep recursion of who knows what.

























Chandler attempts to weaponise Monica's Layer 3 advantage by inviting Phoebe over, unaware he is overplaying his hand.









Phoebe locks in the iconic four-level epistemic loop: Phoebe and Rachel know (1) that Monica and Chandler know (2) that Phoebe and Rachel know (3) that Monica and Chandler are together (4).

Joey's deadpan button confirms that the recursion has completely outrun his working memory.
