Kyle asks his parents what a sex change is, and as she explains the term, his mother, Sheila Broflovski, insists on the legitimacy of cosmetic surgery as an important aid for people whose physical appearance contrasts with their self-image. However, in applauding Mrs. Garrison's courage, she inadvertently implies that Kyle's own problems can be solved in a similar manner. Stan accompanies Kyle to Trinidad to see about the situation, and Dr. Biber suggests that Kyle should undergo a "negroplasty" to make him African-American. When Kyle returns home, his parents are outraged by the suggestion. His dad, Gerald Broflovski, travels to the Institute in order to confront Dr. Biber. However, Dr. Biber, spotting Gerald's dolphin shirt, appeals to his affinity for dolphins and convinces him to undergo "dolphinoplasty", surgically altering his appearance to resemble that of a dolphin. At Mrs. Garrison's home, she comes home and asks Mr. Slave to take her to bed, but Mr. Slave, upset that he was never asked his feelings regarding the operation, refuses and breaks up with her.
