Complete story — includes the ending
When Janice playfully asks the gang if any two of them (other than current couple Ross and Rachel, as well as siblings Ross and Monica) have ever slept together, the gang flashes back to 1993 (one year before the pilot episode), the time when the coffee shop was a bar. The gang's secrets are revealed: Ross and Phoebe nearly had sex on a pool table when the former was depressed after finding out his then-wife, Carol, is a lesbian; Joey mistook Monica's lemonade offer as an advancement and hit on her by getting naked; Chandler tried to hit on Rachel at the bar when he overheard her lamenting to her girlfriends that she might not have anymore casual flings after getting married with Barry. She brushed Chandler off initially, though fantasized about having sex with him while driving later on.
