Tear Jerker: The final scene with Mr. Belvedere and the Owens family in season 6x22, episode #117, part 2 of the series finale, "Mr. Belvedere's Wedding". After he takes one last look at his bedroom, he then says his goodbyes to each member of the family from oldest to youngest. Of course, he saves the best for last with Wesley, whom, despite the often humiliating moments, loved him very much. It's both funny and sad at the same time.
Wesley: "I know I'm losing my best friend."
Mr. Belvedere: "Wesley, I've known heads of state, and many celebrities. But none have given me finer memories than you. I shall savor our moments together. Even the embarrassing and painful ones. Which account for most of them. Though you are an Owens, I shall always think of you as a son."
- The two of them then hug each other. His new wife, Louise, then reminds him it's time to go with her to Africa. After bidding one final farewell, he leaves, and the scenes ends with the family peeping out the front door for one final look, as Wesley states the obvious:
Wesley: "He's gone."
