- “We've secretly replaced this doctor's blood with hepatitis blood. Let's see if he notices!”— Janitor
"My Sacrificial Clam" is the twenty-first episode of Scrubs' first season. J.D. gets jabbed by a needle and fears he might be infected with Hepatitis B, causing him to become afraid of his patients. Turk feels insecure about his weight, and Dr. Cox offers to help him get in shape. Elliot's work life is disrupted because of her new boyfriend, Sean Kelly.
Turk puts on weight and is teased by Carla, which bothers him. Meanwhile, as J.D. and Nurse Roberts check a patient's hepatitis B viral load, J.D. is accidentally stuck by the blood-filled needle. He fears he has been infected and has tests done. While some people are supportive, others, like Dr. Kelso, are less helpful. Janitor mocks him in his usual tone.
Elliot spends the night with Sean, prompting teasing from others in the hospital. Carla tries to reassure Turk that she meant nothing by her joke about his weight, and says that no doctor in the hospital is in shape. Her words are undermined when a very fit Dr. Cox walks by.
J.D. treats four doctors, who scare him by telling stories of their colleagues' getting infected by their patients. Elliot and Sean discuss their sex life. Intrigued by Dr. Cox's fitness, Turk looks to him for advice on how to stay in shape. Dr. Cox mocks him by showing him his "future"—several increasingly overweight African-American men—and then invites Turk to work out with him.
At rounds, Elliot screws up her answers and fears that her relationship with Sean is the cause. She becomes increasingly agitated at Sean, who has no idea why she is angry. J.D. is more and more terrified that he might have hepatitis B. The tests then reveal that he is healthy, but he is still scared by the idea of catching something from a patient. His fear causes him to lose the respect of his peers, and he turns a meningitis patient over to Dr. Cox. Carla, feeling ignored by Turk, asks him to spend time with her. Elliot apologizes to Sean for her outbursts, then realizes that their relationship isn't working and breaks up with him. Dr. Cox refuses to give J.D. back his meningitis patient, and J.D. realizes that Dr. Cox wanted him to get over his fear himself.
- Sick patients are all around J.D., shuffling toward him and making zombie noises.
- J.D. asks Janitor to be nice to him for once, and Janitor starts annoying him by being overly nice. When Janitor invites J.D. to a baseball game, J.D. thinks he is mocking him, but Janitor pulls tickets out of his pocket and tells himself that he will never reach out to J.D. again.
