Quote from Monica in The One with Rachel's Sister
Monica: I have not been sick in over three years. [sneezes] Chandler: I'm going to grab you some tissues. Monica: I don't need a tissue. I'm fine-d. Ross: When you put a "D" at the end of fine, you're not fine. Monica: I'm fine-d. I'm fine-d. You know, it's a really hard word to say.
