The One with Phoebe's Cookies

S7, E3: Rachel tries to teach Joey how to sail his boat but turns into an overbearing perfectionist. They both decide it's more fun to sit in the boat at the dock and drink beer. Chandler plays racquetball with Monica's father and accidentally sits on his lap in the steam room...while they're both naked. Monica tries desperately to reproduce Phoebe's grandmother's secret cookie recipe only to discover that they are simple Nestle's Tollhouse cookies and the recipe is right there on the package.
