Friends, Season 7

Ross:
[quietly to Chandler] How could you tell her?!

Chandler:
I had to! We're getting married! Couples can't keep secrets from one another!

Ross:
Well, I guess Monica should know about Atlantic City!

Chandler:
DU-UUUDE!!

Monica:
What happened in Atlantic City?

Ross:
Chandler and I are in a bar...

Chandler:
Did you not hear me say "DU-UUUDE"?!

Ross:
...and this girl is making eyes at him. After a while he goes over to her, and a minute later I see them kissing. Now you're thinking, "Chandler's not the type of guy who just goes to bars and makes out with girls!" And you're right, he's not the type of guy who just goes to bars and makes out with girls! [widens his eyes]

Monica:
You kissed a guy?!

Chandler:
In my defense, it was dark and he was a very pretty guy!

Ross:
I laughed so hard...

Chandler:
...that we had to throw out your underwear again?!

Ross:
Whatever, dude! You kissed a guy!
