Ex Input:
Speaker 1: Hey.
Speaker 2: So how was Joan?
Speaker 1: I broke up with her.
Speaker 1: They were huge. When she sneezed, bats flew out of them.
Speaker 3: Come on, they were not that huge.
Speaker 1: I'm tellin' you, she leaned back, I could see her brain.
Speaker 2: How many perfectly fine women are you gonna reject over the most superficial insignificant things?
Speaker 4: Hold it hold it. I gotta side with Chandler on this one. When I first moved to the city, I went out a couple of times with this girl, really hot, great kisser, but she had the biggest Adam's apple. It made me nuts.
Speaker 1: You or me?
Speaker 5: I got it. Uh, Joey, women don't have Adam's apples.
Speaker 4: You guys are messin' with me, right?
Speaker 6: Yeah.
Speaker 4: That was a good one. For a second there, I was like, "whoa."
Speaker 7: You name one woman that you broke up with for a real reason.
Speaker 1: Maureen Rosilla.
Speaker 5: Not hating Yanni is not a real reason.
Speaker 1: Ok, Janice. Janice. You gotta give me Janice. That wasn't about being picky.
Speaker 5: We'll give you Janice.
Speaker 7: I miss Janice though. "Hello, Chandler Bing."
Speaker 3: "Oh, my, god."
Speaker 4: "Oh, Chandler, now, now, that's it. There, faster!"
Speaker 2: Stop with the broom, we're not making noise.
Speaker 3: We won. We won! Joan is or was dating which Speaker?

Ex Output:
Speaker 1

Ex Input:
Speaker 1: Your ex-boyfriend is insane.
Speaker 2: Did you get the grant?
Speaker 1: No I didn't, and you want to know why? Because your ex-boyfriend is still in love with you.
Speaker 2: What?
Speaker 1: Yeah. He wouldn't give me the grant, because I wouldn't give you up.
Speaker 2: Benji isn't in love with me. I mean, he broke up with me. And besides, he's a very ethical man.
Speaker 1: Really? Is it ethical to ask someone in a grant review, who was the voice of "Underdog"?
Speaker 2: I'm sure he was just joking, Ross.
Speaker 1: If you don't believe me, let's go talk to him, okay? I'm telling you, he didn't ask me one paleontological question.
Speaker 2: Seriously?
Speaker 1: Oh, I'm sorry, no. He did ask me one. Uhm... How do you spell Mboscodictiosaur?
Speaker 2: Well, if it's like the lake Mbosco in Congo, then M-B-O...
Speaker 1: Damnit! Benji is or was dating which Speaker?

Ex Output:
Speaker 2

Ex Input:
Speaker 1: I mean if you think about it, I mean Ross did learn something from each marriage.
Speaker 2: How to make the next one even shorter?
Speaker 1: Now wait a minute that's not fair. He was married to me a hell of a lot longer than he was married to Emily, he just didn't tell me. Maybe I have to pee again.
Speaker 2: Well, this is fun. So Ross, did you kill any of these wives?
Speaker 3: Y'know what? I-I-I... I-I have had enough of this! Y'know, I-I-I care a great deal about your daughter and I have treated her with nothing but respect! So if-if you've got a problem with me, frankly...
Speaker 2: Are you yelling at me?!
Speaker 3: God no!
Speaker 4: Y'know what daddy? If you don't like Ross, that's fine. It doesn't matter to me, I'm gonna go out with him anyway.
Speaker 2: Really?!
Speaker 3: Well if it doesn't matter to her, it doesn't matter to me! Still not yelling!
Speaker 2: Wow. What can I say? This doesn't make me like you any better!
Speaker 3: That's okay, I'm not so crazy about myself right now either.
Speaker 2: Then we agree?
Speaker 3: Uh yeah, I guess-Yeah! I guess so.
Speaker 2: Neither of us like Ross!
Speaker 4: I like Ross.
Speaker 3: Ohhh! Kids!
Speaker 1: Wait-wait-wait, I just thought of another story about how nice Ross is!
Speaker 3: That's okay Rach, we're not liking Ross right now.
Speaker 1: Oh! I've got a lot of those too! Speaker 3 is or was dating which Speaker?
