- For Rachel's colleague see Mark Robinson.
Marc Coreger appeared in "The One Where Rachel Has A Baby, Part 1", portrayed by Tim DeKay.
Marc and his wife, Julie share a semi-private labor room with Rachel and Ross. At first the couple seems quite friendly and helpful but soon proves to be a little too eager about the process of birth.
They are so overly enthusiastic about pregnancies that it eventually creeps out both Rachel and Ross. Instances of this are when he takes pictures of Rachel having contractions and describing his wife's cervix in graphic detail. Soon after this, he and his wife get transferred to the delivery room leaving Rachel and Ross with a new couple.
After they leave, Ross refers to them as "The Disgustingtons."
