10 Most Annoying TV Plot Holes Ever

10. Phoebe's Dad Ran Out On Her Before She Was Born, But Somehow Sang Her Lullabies - Friends

The character of Phoebe Buffay didn't have what you'd class as the most idyllic upbringing. On top of her step-father going to prison and her mother committing suicide when she was young, the eccentric member of everyone's favourite friendship group was abandoned by her father before she was even born. Or at least that's what we were told early into Friends' run on NBC.

However, by the time we get to Season Five, Phoebe comes face to face with her biological father and things get a little confusing. Frank Buffay Sr. explains to Phoebe that he was a terrible father. He burned baby formula, couldn't put their nappies on right, and would often make them cry when singing his rather familiar made-up lullaby - Sleepy Girl.

All this points to a father who was most definitely around his twin daughters for a while before deciding he wasn't cut out for the job. In fairness to Pheebs, she did wind up homeless at 14 and contracted hepatitis after a pimp spit in her mouth, so you can probably forgive her for getting her wires crossed when it came to recalling exactly when daddy did a runner.
