Ross, chandler and joey are in central perk, when a girl  walks in,  they are all sitting on the orange sofa when they notice her. joey attempts the 'How you doin' catchphrase but sadly it doesnt work. The girl walk over to get a coffee  
and starts chatting to Gunther, the sliightly nervous bartender who is in love with Rachel Greene who has an on/off relationshup with Ross. Gunther starts to chat to the pretty woman. meanwhile the guys on the sofa start wondering why gunther suddenly is chatting women up when he couldnt talk to anyone in 10 years
