Phoebe is dreadful and breaking up Ash and Denny just to give her a reason to stick around is one of the worst recent decisions. (Poor Denny, first she got stuck with Casey for no reason other than so she could cry a lot when he died, now she's been shunted aside to make room for the writers' incredible delusion that Phoebe is a good character and we all love watching her.) Mind you, Hannah does give Phoebe a very very good run for her money in the annoying stakes. How on earth she managed to convince people she was a decent guardian for Evelyn and Oscar for so long is another of the show's great mysteries.
