The One with Rachel's Phone Number

S9, E9: Rachel and Phoebe go out for a night together. After Rachel impulsively gives a handsome restaurant patron her telephone number, she worries that he'll call when Ross is in their apartment. While the women are away, Phoebe's boyfriend, Mike (recurring guest star Paul Rudd), helps Ross baby-sit for Rachel's baby--and the guys desperately try to find something in common to talk about. Also, still working in Tulsa, Chandler returns to New York to visit Monica, but he must hide from Joey after rejecting his offer of free basketball tickets.
