Quote from Chandler in The One Where Ross Got High
Chandler: Hey. Oh, good, Ross. Your parents like me, right? Ross: Yes, of course they like you. Chandler: Well, Monica just told me that they don't. Ross: Yeah, they don't like you. Chandler: Do you know why? Ross: I don't know. Maybe it's because you're really sarcastic or maybe it's because you- Chandler: Well, if people don't know, they shouldn't just guess.
