- “I'm okay, I'm okay, I'm okay, I'm akay, I'm a kay. I'm a kay? What the hell does that mean?”— J.D.
"My Tuscaloosa Heart" is the eighteenth episode of Scrubs' first season. J.D. worries that his neglect caused a patient's death. Turk, Elliot, and Carla discover that Dr. Kelso wrote love songs when he was younger.
J.D. has a cancer patient, Aaron Simon, who is rude to him and the nurses. When Mr. Simon eventually dies from his illness, J.D. worries that he neglected the man and caused his death. Although a Morbidity and Mortality conference clears him of any fault, he still feels guilty, until Dr. Cox assures him that all doctors face these thoughts.
Dr. Cox's own problems come in the form of his complicated love life: He is dating and falling in love with Kristen Murphy, a surgical student, just as his ex-wife, Jordan, reappears demanding sex—and there is also his crush on Carla. After he sleeps with Jordan and blows off a date with Kristen to help Carla move a dresser, he decides that he has a problem and should commit himself more fully to Kristen. Shortly after this decision, however, Kristen learns about Jordan and Carla and breaks up with Dr. Cox anyway.
Meanwhile, Elliot is convinced that Dr. Kelso is the man singing country songs (including one called "My Tuscaloosa Heart") on a tape given to her by a patient. Turk doesn't believe it, until Kelso uses the phrase "my Tuscaloosa heart" in conversation. Both of them now wonder why all of the love songs star someone named "Bunny" instead of Kelso's wife. When they finally ask him, he denies being the musician on the tape and tells an obviously fabricated story claiming to be Elvis Presley. However, it is later revealed that Kelso was lying; "Bunny" is his nickname for his wife.
