Friends: 10 Most Insane Things Phoebe Has Done
3. She Dated Her Sister's Exes
Not once but twice Phoebe found herself falling for men who had previously dated her sister Ursula. On both of these occasions she learned the hard way that dating people who had been in love with her twin is perhaps not the most sensible of choices.
In season 3 Phoebe realises she is being followed and confronts the man stalking her. He turns out to be an ex boyfriend of Ursula named Malcolm who had accidentally begun to follow Phoebe instead. She finds herself drawn to him and begins a relationship with him in an attempt to distract him from her sister. Although Phoebe realises the situation is too weird she does offer to help him get over his obsession.
Following this, in season 8, Ursula arrives at a party with her fiancé Eric. Quickly Phoebe realises that Ursula is lying to him about almost everything and informs Eric of this. They break up and he confides in Phoebe, this relationship develops and they end up kissing. However, Phoebe leaves the room and Ursula comes in, Eric then has sex with URsula believing her to be her sister.
Luckily both these relationships crumbled almost as quickly as they developed but Phoebe's sanity has to be questioned.
