(Joey has realized that Monica and Chandler spent the weekend together, so they drag him into Monica's bedroom before he blows their secret)
Joey: (pointing to Chandler) You? (then to Monica) ...and you?!
Monica: Yes. But you can't tell anyone. No one knows.
Joey: How?! When?!
Chandler: It happened in London.
Joey: In London?!!
Chandler: Shhh! The reason we didn't tell anyone was because we didn't want to make a big deal out of it.
Joey: But it is a big deal! (climbing off the bed) ...I have to tell someone!
Chandler: (wrestling him back onto the bed) You can't!
Monica: Please! Now, we know this is hard...
Joey: It is! ...It hurts!
