Elliot finally works up the courage to tell Keith that the wedding is off, as the entire Sacred Heart gang watches from second-story windows. That night, J.D. returns home to Kim, happy that he didn't screw things up with her.
At work the next day, Elliot has a hard time dealing with Keith's anger toward her and decides to talk to him about it. Meanwhile, Turk tells J.D. that he doesn't have real feelings for Kim and their relationship is a sham built on the fact that she' pregnant. J.D. disagrees and says that when Turk sweats, he smells like eggs.
Cox diagnoses patient Joe with Lyme disease and there's a sparkle of friendship between them. As Turk drinks water and pours sweat, Cox admits that, "I think I like him." Kelso walks by and wonders what smells like eggs as Turk consults Cox on patient/doctor relationships.
Elliot has her talk with Keith while he's packing up his stuff in her house. She tries to make him laugh, but he only gets angrier. At the hospital, J.D. tells Cox that he always sabotages himself when it comes to women. They're interrupted by "Fun Size," who tells Cox that she couldn't find a tick bite on Joe.
Turk can't figure out what's wrong with Joe, but he knows one thing for sure: he really likes Joe and thinks that he has a "magical quality" about him. Both Turk and Cox are sad when Kelso tells them it's time to check Joe out of the hospital. However, Turk and Cox smuggle Joe into dermatology instead.
When Kelso finds out that Turk and Cox haven't released Joe, he goes himself to tell Joe to get out. But when Kelso gets a look at Joe's disarming smile, he too gets the Joe bug. Kelso sits down with Turk and Cox to figure out what's wrong with lovable Joe.
J.D. is proud of going an entire day without sabotaging himself... until he falsely accuses the janitor of having a make-believe girlfriend named "Lady," which actually turns out to be true! That afternoon, Carla tells Elliot and J.D. to give themselves a break... they're only human.
For the second time, Elliot breaks up with Keith as J.D. gets a call from Kim and realizes that he doesn't miss her; he's only with her because he got her pregnant. But J.D. will stay with her till the very end, whether he loves her or not.
