I always thought that Ross and Rachel are so funny when they drunk!! That's why I put up this section.

Now, let's start when Ross drunk :

Season 1, Ep. 8 : ~The One Where Nana Dies Twice~

Phoebe: Hey, look who's up! How do you feel?
Ross: I feel great. I feel- great, I fleel great.
Monica: Wow, those pills really worked, huh?
Ross: Not the first two, but the second two- woooo! ...I love you guys. You guys are the greatest. I love my sister [Kisses Mon], I love Pheebs.. [Hugs her]
Phoebe: Ooh! That's so nice...
Ross: ...Chandler!
Chandler: Hey.
Ross: [Hugs him] And listen, man, if you wanna be gay, be gay. Doesn't matter to me.
Andrea: [Turns to a friend] You were right. [They walk off and leave Chandler.]
Ross: Rachel. Rachel Rachel. [Sits down beside her] I love you the most.
Rachel: [Humouring him] Oh, well you know who I love the most?
Ross: No.
Rachel: You!
Ross: Oh.. I don't get it! [Passes out and slumps across her]

Next, when Rachel get drunk :

Season 2, Ep. 7 : ~The One Where Ross Finds Out~

MICH: I don't know if Monica told you but this is the first date I've gone on since my divorce so, if I seem a little nervous, I am.
RACH: [distracted] How long do cats live?
MICH: [confused] I'm sorry?
RACH: Cats, how long do they live figuring you don't... y'know, throw 'em under a bus or something?
MICH: Um, maybe 15, 16 years.
RACH: That's just great. [she picks up her champagne and starts drinking]
MICH: Um, cheers.
RACH: Oh, right, clink. [downs her glass]
MICH: Monica told you I was cuter that this, didn't she?
RACH: Oh, no, Michael, it's not you. I'm sorry, it's just, it's this thing. It's probably not as bad as it sounds but this friend of mine is, is getting a cat with his girlfriend.
MICH: Oh, that does sound. . .(realizes and get confused)....Ahh.
RACH: I mean he just started going out with her.
MICH: Is this guy, uhh, an old boyfriend?
RACH: Ah, hah-hah-hah-ho, yeah, he wishes. Oh, I'm sorry, look at me. OK, Michael, let's talk about you.
MICH: Alright.
RACH: OK, OK. So, you ever get a pet with a girlfriend?
(Time lapse)
RACH: [obviously drunk] I mean, it's a cat, y'know, it's a cat. Why can't they get one of those bugs, y'know, one of those fruitflies, those things that live for like a day or something? [belligerently] What're they called, what're they called, what're they called?
MICH: Fruitflies?
RACH: Yes! Thank you.
[The waiter comes to the table.]
WAITER: So, would you like any dessert?
MICH: No! No dessert, just a check, please.
RACH: Oh, you're not having fun, are you?
MICH: No, no, I am, but only because for the last hour and a half I've been playing the movie Diner in my head.
RACH: Oh, look at me, look at me. Oh, I'm on a date with a really great guy, all I can think about is Ross and his cat and his...Julie. I just want to get over him. gosh, why can't I do that?
MICH: Oy. Look, I've been through a divorce, trust me you're gonna be fine. You just can't see it now because you haven't had any closure.
RACH: Yeah! Closure. That's what it is, that's what I need. God, you're brilliant! Why didn't I think of that? How do I get that?
MICH: Well, you know, there's no one way really, it's just, you know, whatever it takes so that you can finally say to him, "I'm over you."
RACH: Closure, that's what it is. Closure. [she looks around the restaurant, spotting a guy with a cellular phone] Hello, excuse me. Excuse me, hel. . . woo [she almost falls out of her chair]
GUY: Hang on.
RACH: Hello, excuse me.
GUY: What.
RACH: Hi, I'm sorry, I need to borrow your phone for just one minute.
GUY: I'm talkin'!
RACH: I can see that. I... just one phone call, I'll be very quick, I'll even pay for it myself. [man is still reluctant] OK, you're bein' a little weird about your phone.
GUY: Alright, fine. [on the phone] I'll call you back. [hands the phone to her]
RACH: Thank you. OK. [dials] [to Michael] Machine. Just waiting for the beep.
MICH: Good.
RACHEL: [on phone] Ross, hi, it's Rachel. I'm just calling to say that um, everything's fine and I'm really happy for you and your cat who, by the way, I think you should name Michael. And, you know, ya see there I'm thinking of names so obviously, I am over you. I am over you and that, my friend, is what they call closure. [hangs up and tosses phone in the ice bucket]

And the last one (at least until now) when both of them get drunk together!!

Season 5, Ep. 24 : ~The One In Vegas~

Rachel: Hit me. (He does so.) Hit me. (He does so.) Hit me. (He does so.) Hit me. (He does so.) Hit me. (He does so.) Hit me. (He does so.) Hit me. (She slows down with each one.)
Ross: (runs out of cards) We need more cards.
Rachel: Yeah, and also we need more umm, drinks. Hold on a second. (Gets up but stumbles a little bit.) Whup, okay. (She makes it to the phone and picks it up, without dialing.) Hello! Vegas? Yeah, we would like some more alcohol, and y'know what else? We would like some more beers. Hello? Ohh, I forgot to dial!
(They both start laughing. There's a knock on the door.)
Ross: That must be our alcohol and beers! (Gets up to answer it.)
Joey: Hey!
Ross: Ohh, it's Joey! I love Joey! (Hugs him.)
Rachel: Ohh, I love Joey! Joey lives with a duck! (Goes and hugs Joey.)
Joey: Hi!
Rachel: Hey!
Joey: Look-look-look you guys, I need some help! Okay? Someone is going to have to convince my hand twin to cooperate!
Ross: I'll do it. Hey, whatever you need me to do, I'm your man. (He starts to sit down on the bed. There's one problem though, he's about two feet to the left of it. Needless to say, he misses and falls on his butt.) (Looking up at Joey.) Whoa-oh-whoa! Are you, are you okay?
Joey: Yeah! I'm fine! Thanks! (He starts to leave, but gets an idea and stops.) Hey Rach, how you doin'?
Rachel: I'm doin' good, baby. How you doin'?
Joey: Ross, don't let her drink anymore! (Exits)
Ross: Ohh, here's that Macadamia nut!
Rachel: Ohhh!!
Ross: (he puts it in his mouth) Nope! Something else. (Throws it back under the bed.)
Rachel: Oops! All right, so what do you want to do now?
Ross: I wanna get out of the room! Y'know, I…I really miss downstairs.
Rachel: Okay, y'know what? There's only one way I'm leaving this hotel room.
[Cut to the casino, a very drunk and doodled on Rachel is walking arm in arm with an equally drunk and doodled on Ross are walking through the casino and greeting people on their way through. Ross has some whiskers and his nose colored in, along with his name on his forehead.]
Ross: Well hello! I'm Ross!
Rachel: Good luck to ya!
Ross: Excuse me sir, you've got a little something right here. (He points to the corner of his mouth and they both laugh.)
(They've made their way to the statue of the naked man that Chandler was leaning against earlier.)
Rachel: Wow!
Ross: (bowing) Hello!
Rachel: (bowing) Hello!
Ross and Rachel: (bowing) Hello!
(They both continue on and Ross meows like a cat.)
