The Kwans are a couple that live near Sacred Heart Hospital.
When Janitor told J.D. that he wanted to be friends and J.D. believed him, Janitor asked him to help him move. In the end, it turns out that Janitor pranked J.D. into stealing items from the Kwans. J.D. steals a Buddha statuette and outruns the Sheriff's K-9 unit. Eventually, J.D. gives back the Buddha statue with a sign that says "I missed you!".
