1. undies 内裤 

Phoebe 在沙发上发现了Chandler的内裤，一边扔一边喊undies。

Undies是对内裤 underwear的简称。

男士的平角内裤还可以用boxer 

Phoebe: What am I sitting on?

Chandler: Top of the world? Dock of the bay? (He tries to think of another but can't) I'm out.

Phoebe: (taking something out of the couch) Ew-eww!! Undies!

Rachel: All right! Who's are they? Who's are they?

Ross: Well, they're not mine!

Chandler: Well, they're Joey's! They gotta be Joey's!

Joey: Yeah, they're mine.

Chandler: See? They're Joey's! J-J-J-J-J-Joey's!

2. a word? 能跟你说句话么？ 

Joey替Chandler背锅后对Chanlder说A word? 

a word = Can I have a word with you? 借一步说话

类似的说法还有 Can I see you for a second? 

Rachel

: (waving them in his face) Take 'em! (Joey makes a noise and jumps out of the way.) Joey, you can touch them! They're your underwear.

Joey: (reluctantly taking them) Chandler? A word.

Joey: That's it! I'm tired of covering for you two! This has got to stop! 

3. one thing leads to another 前因后果 

因为Rachel发现了Monica落在Chandler那里刮腿毛的razor, Joey只能说是自己的，结果为了自圆其说真的把腿毛给刮了。发现razor到刮腿毛Joey用了one thing led to another. 

One thing leads to anthoer 一件事导致另一件事。前因后果

Monica: (entering) Thank you Joey, thank you so much!
