I don't know if the following is a spoiler for anyone who hasn't seen all of Season 6 but I'll put one in anyway just to be sure ..... Spoiler Space... .. .. .. .. .. .. .. ..
In several early episodes Phoebe says that her real dad ran out on 'her,Ursula and her Mum before she and Ursula were born'. But in the episode 'TOW with Joeys Bag' her Dad says "how are the girls" and "I was never much of a father" - if he ran out before Phoebe was born he wouldn't have had the chance to be a father and wouldn't have known that his babies were girls. Does this make sense to anyone else?
