I thought this one was pretty funny. Here are my favorite scenes:

(Phoebe enters with Hums While He Pees also known as Kyle.)
Phoebe: I’m having a really good time!
Kyle: Me too! I’m sorry that guy in the subway licked your neck.
Phoebe: Ohh. No that’s okay, he’s a friend.
Kyle: Hey uh, I don’t mean to be presumptuous but I have these two tickets to the ballroom dancing finals tomorrow night if you want to go?
Phoebe: Yeah, I… Well y’know I-I mean I missed the-the semi-finals, so I’d just be lost.
Kyle: I know it’s really lame, but I got these tickets from my boss and—Oh no! No! No! My God!
Phoebe: Okay, don’t freak out. I’ll go.
Kyle: No it’s… Uh, my ex-wife Whitney is out there. I cannot deal with her right now. That woman is crazy!
Phoebe: Okay, I know. Hold on. (She walks over to the couch.) Hey Ross?
Ross: Yeah?
Phoebe: Yeah, umm that’s Whitney (Points), Kyle’s ex-wife out there, now do you think that you can y’know divert her so that we can slip out?
Ross: What?! No!
Phoebe: Well okay but I have two tickets to the ballroom dance finals. (She holds up the tickets that Kyle gave her.)
Ross: Look, I don’t think so Pheebs. (Pause) All right, I’ll do it. But just because you’re a friend. (Grabs the tickets and heads to divert Whitney.)

[Scene: Ross's apartment, Ross is dancing around his living room as Phoebe enters, catching and startling him.]

Phoebe: Hi Ginger.
Ross: All right! I want my key back!
Phoebe: I don’t have it!
Ross: It’s right there! (Points to her hand.)
Phoebe: Ugh, okay Sherlock! (Hands over the key.)
Ross: Look, I’m sorry but you-you-you better go Pheebs.
Phoebe: All right, well I just wanted to say thank you though, for diverting Kyle’s ex.
Ross: Oh yeah—No—You’re welcome. We’ll talk about it later.
Phoebe: Okay.
(Ross opens the door to reveal Whitney standing there.)
Ross: Hi Whitney.
Whitney: Hi Ross! You ready for breakfast?
Ross: Yep. (Phoebe slams the door shut.) Okay.
Phoebe: (To Ross) Kyle’s ex-wife? You were supposed to divert her, not date her!
Ross: (opens the door and to Whitney) Hi! I’m sorry, but can you give me a second while I talk to this woman, who by the way did not spend the night?
Whitney: Sure.
Ross: Okay. (Closes the door.) (To Phoebe) I did divert her and we ended up having a great time! Okay?
Phoebe: Watching ballroom dancing?
Ross: Yes! That’s where we realized we were both super cool people!
Phoebe: Well look-look, okay Ross, Kyle just told me some really bad stuff about her.
Ross: Like what?
Phoebe: Like she’s really mean, and she’s over critical, and-and—No! She will paint a room a really bright color without even checking with you!
Ross: Okay.
Phoebe: And! She uses sex as a weapon!
Ross: Fine! Thank you for warning me. At breakfast I’ll be on full alert for room painting and sex weapons.
Phoebe: You’re still gonna go out with her?!
Ross: Yeah!
Phoebe: Well, didn’t you just hear what I said?!
Ross: Pheebs come on! I mean, consider the source! Of course her ex-husband’s gonna say that stuff. Now, if you’ll excuse me…
Phoebe: (interrupting him) No listen to me! She is crazy!
Whitney: (outside the door) Uh, your door isn’t sound proof.
Phoebe: You see? Nothing is good enough for her!

That was good. Then came this:

[Scene: Central Perk, Ross and Phoebe are there.]

Phoebe: Hi.
Ross: Hi.
Phoebe: So, how are things going with crazy? Has she cooked your rabbit yet?
Ross: Listen, you are hearing one side of the story, okay—and F.Y.I she must’ve shown Kyle over 30 paint samples before she painted that room! And his response to each one was, "I don’t give a tiny rat’s ass."
Phoebe: Yeah well, maybe she should’ve spent a little less time decorating and a little more time in the bedroom.
Ross: Well, I don’t think we are gonna have that problem, but maybe that’s just because I am not emotionally unavailable!
Phoebe: You think he’s emotionally unavailable?
Ross: I think he can be.
Phoebe: Well, maybe he wouldn’t be if she didn’t bring the office home every night!
Ross: Well, excuse her for knowing what she wants to do with her life!
Phoebe: Yeah well, she certainly knew what she was doing New Year’s Eve 1997.
Ross: (angrily) I knew you were gonna throw that in my face!! That was three years ago! She apologized and she apologized! What more do you want?!!
Phoebe: (gets up and starts to leave) We want the last six years back!!
Ross: So do we!! So do we!! (Ross notices a couple has been staring at them.) I’m sorry you had to see that.

And finally:

[Scene: Central Perk, Ross and Phoebe are there again, only now they’re not talking to each other. Phoebe is loudly stirring her coffee.]

Ross: My God!
Phoebe: Oh, I’m sorry. Is that annoying? And speaking about being selfish in bed, how’s Whitney?
Ross: Well maybe she wouldn’t have to be selfish in bed if someone else knew where everything was!
Phoebe: Oh he knows! (Quietly) For the most part.
(Kyle and Whitney enter.)
Kyle: Oh hey! Good, you’re both here.
Whitney: We kinda need to talk.
Phoebe: Both of you together?
Ross: Wh-what’s up?
Whitney: Well, I went over to Kyle’s last night to pick up a few things and we got to reminiscing…
Kyle: …we talked through most of the night and we realized that the reason we were so angry at each other was because there are still feelings there. So… (Pause)
Ross: Oh just say it Kyle!
Kyle: We’re gonna give it another try.
Phoebe: What about her whining and her constant need for attention?!
Whitney: I’m gonna work on that.
Phoebe: Oh right, because you’re so capable of change.
Ross: (To Whitney) Y’know, he hums when he pees!
Whitney: I do know.
Ross: It makes him miss the bowl, but whatever.
Whitney: We’re so sorry. (They get up to leave.)
Ross: That’s all right, we-we don’t need you. In fact, hey I’m over it already.
Phoebe: Yeah, and y’know what? I don’t give a tiny rat’s ass.
Kyle: Yeah, we’re gonna go. (They leave.)
Ross: (To Phoebe) I’m sorry. Ugh, Pheebs, you were, you were right about her. Y’know, she did try to use sex as a weapon! Yeah, I hurt my back a little.
Phoebe: Oh. Y’know, he hums while he does other stuff, too.
Ross: Yeah, we're better off without them.
Phoebe: And y’know, even if they break up again, you’d better not let him in your sad men’s club!
Ross: Divorced men’s club.
Phoebe: Potato, Potaato. (She’s pronounces potato with the both the short and long As.)

Well, that was funny! The blooper reel for this one is great, both Dave and Lisa are cracking up when they try to deliver the dialogue, it took them quite a few times to get it right!

But it seemed to me that both Ross and Pheebs were being a tad bit selfish in this one. I would date Whitney, she could inflict as much sex on me as she wants to! (It might hurt a bit, but hey, I'm game!)

Just saw this one again. Remember the part where Rachel is discussing her crush on Tag, and admits that she had one on Joey when they first met? Funny, I thought that was Monica, which of course goes away when he "takes it out!" We saw that happen in "The One With The Flashback" in season three. And then Chandler asks Rachel if she had a crush on him when they first met, and she stumbles over her answer before non-convincingly saying "yeah, sure". Uhhh, she must have a REALLY bad memory cuz she most certainly DID have a crush on Chandler when she met him! Once again, "The One With The Flashback" confirms that Rachel fantasizes about having sex with him while she is driving back to whereever with her girlfriends after visiting the bar which would become Central Perk. And then of course, she runs out on Barry and the wedding and enters it to find our other friends gathered there, in the pilot.

The events in that "original flashback" episode contradicts the dialogue in this one. Isn't that just the damndest? I sure think so!
