Dr. Nick (The Simpsons)

Dr. Nick Riviera, usually referred to as Dr. Nick, is a recurring fictional character in the American animated sitcom The Simpsons. He is voiced by Hank Azaria, and first appeared in the episode "Bart Gets Hit by a Car". Dr. Nick is an inept quack physician, and a satire of incompetent medical professionals. Dr. Nick is known for his exclamation of "Hi, everybody!" upon entering a scene, which is immediately followed by the other characters present with, "Hi, Dr. Nick!", with one exception: in "Who Shot Mr. Burns?", Mr. Burns replies with "Ho, Mer. Simp-son", but with the same inflection as the usual greeting.
