1. Ex-con 有犯罪前科的人 

Rachel对于独自照看Ben感到紧张，Ross说Ben又不是个ex-con. 

Ex-con 有犯罪前科的人。

Con有几种意思，常见的意思是骗局，conman 就是骗子。Con还有反面反对的意思，以前提到过的pros and cons 利弊

Ross: Hey listen can you do me a big favor? The dean’s office just called and said there was an urgent meeting. Can you watch Ben for like an hour?

Rachel: What-what about Monica?

Ross: Oh, she isn’t home.

Rachel: (nervous) So it would just be me alone?

Ross: Well, Ben would be there.

Rachel: Huh umm…

Ross: What’s the matter?

Rachel: Well that—y’know it’s just uh, I’ve never done that before. Me and him alone.

Ross: Rach, he’s not an ex-con.

2. call it 我定了

Monica和Chandlder的结婚典礼找不到主持的牧师，Phoebe说其实可以从网上获得婚礼主持的资格，Joey大喊I call it. 

call it 意思是我定了，我要了，这事儿是我的。

类似的美语口语还有dibs. 比如一个人对大家说Who want the last piece of cake? 一个人大喊Dibs. 我的了！

Phoebe: Oo! You should have one of us do it!

Monica: Phoebe, we’re getting married, married; not sixth grade married.

Phoebe: No! No! It’s-it’s uh a real thing! Anyone can get ordained on the Internet and perform like weddings and stuff!

Monica: Are you serious?

Phoebe: Yes! A friend of mine did it and it’s totally legal!

Joey:I call it!!

Phoebe: What?! No! It was my idea!
