The One With Phoebe's Cookies - S7-E3
Corrected entry: Phoebe says that her Grandma gave the cookie recipe to her 'on her deathbed', yet in series 5 Phoebe says that her grandmother died suddenly on a shopping trip, rather than from a long illness or old age as she suggests.
Correction: People generally have two grandmothers. Just because her father ran off, doesn't mean that his mother abandoned her grandchildren so readily.
