Stephen Moon is an essentially one-shot character on Frasier. He is the favorite brother of Daphne Moon. He appears in the series finale "Goodnight, Seattle" where he is played by Richard E. Grant. He also appears in the episode "And the Dish Ran Away with the Spoon", but was played by a different actor and had no speaking lines, not even being clearly identified amidst the scrum of Moons.
