 They discuss what to get Monica and Chandler as engagement presents and Monica really wants Phoebe s grandma s chocolate chip cookie recipe. Phoebe s grandma made Phoebe swear never to let the recipe out of the family but agrees to give it to Monica. Unfortunately, the fire in Phoebe s apartment destroyed the recipe and Phoebe gives Monica and Chandler the only cookie left as a present. Monica tries to figure out the recipe from the cookie and makes heaps of different ones. Rachel tries to teach Joey how to sail which proves to be quite difficult. Chandler wanted to bond with Mr. Geller but when they went to the steam room after their racquet ball game Chandler accidentally sits on Mr Geller s lap. Monica finds out that Phoebe s grandma didn t have a secret recipe. Monica realizes that she probably got the recipe for Toll House cookies from the back of the Nestles chocolate chip bag, because Phoebe says that her grandma got the recipe from her French friend "Nestle Toulouse". Chandler clears things up with Mr. Geller and Rachel gives up teaching Joey and enjoys Joey s way of sailing: sitting on the boat in the marina drinking beer.
