While trying to get over Janice, Chandler ends up in the arms of one of Joey's sisters, but he can't remember which one. While looking for a job, Rachel stumbles upon Mark, a handsome man, who offers her help with getting a job at Bloomingdale's, after hearing her conversation with Monica.
This episode is actually really good, I enjoyed all the funny scenes with Chandler trying to figure out who is the sister he was with. We can also see Joey in a different role, because we don't see his family that often.
Also, Mark is introduced in this episode, and he is going to have quite a huge impact on Ross's and Rachel's relationship in the future. Anyway, this is yet another great episode.
