Since he isn't Jewish, Steve is lost when Susan invites him over for Yom Kippur leftovers, and asks Patrick and Jeff whether or not you're supposed to give presents on that holiday -- which leads to a misunderstanding with Sally, who was eavesdropping. Meanwhile, Jane decides to take up charity work to prove to the others that she's a giving person.

Patrick wants to break up with his date, because she is too hard on his nipples. Sally seeks to uncover the mystery of why her date is insistent on her not wearing makeup. Steve and Susan decide to start things anew by hooking up as if it were for the very first time. And Jane picks a bad time to chat up her co-worker.
