Continuity: In "The One With Phoebe's Birthday Dinner", which aired in 2002, Ross claims Rachel hasn't cooked since 1996. But in this episode, which aired in 1999, she makes her infamous "trifle".
Goof: When Rachel makes half an English Trifle and half a Shepherd's Pie, it is credited to the pages being stuck together. Considering that the layer of beef sautéed with peas and onions is in the middle of the concoction, this is impossible. There is no way Rachel could have been instructed to add other layers, such as bananas and whipped cream on top.

Goof: When they showed the inside of Rachel's old room there is not much furniture to sit on. There is just a small chair, but when Phoebe walked out of the room she told Rachel that she was just starting to take her "Thanksgiving nap". What was she going to sleep on?
Note: The "small chair" is actually an easy chair that would be suitable for taking a nap. Perhaps not as comfortable as a bed, but it's not like she would be sleeping on the floor or on a straight-back chair.
Factual Error: In this episode, everyone says that Rachel accidentally mixes the ingredients of an English Trifle recipe and a Shepherd's Pie recipe when making her dessert. Actually a Shepherd's Pie is made with lamb. Rachel's "beef-custard thing" is half a Cottage Pie, which is made from beef, and half an English Trifle.
Note: Although it may be true in England where the dish originated, in America the name "Shepherd's Pie" refers to a dish made almost exclusively with ground beef. For that matter, a traditional English trifle is usually made with cake, not ladyfingers, and a fortified wine such as Sherry or Madeira, not rum. But, heck, it's all good (as Joey would undoubtedly agree).
Rachel: Monica said I could make dessert this year.
Joey: Uh, you're gonna cook something?
Rachel: Hey, I cook.
Chandler: Offering people gum is not cooking.
Monica: (referring to her parents) They don't like you. I'm sorry.
Chandler: What? Why?
Monica: Maybe because you used to be aloof or that you're really sarcastic or that you joke around all the time or that you take off your clothes and throw them on the couch.
Chandler: Is this why they don't like me or why you don't like me?
Chandler: Hey, I can be pretty charming, babe, I won you over, didn't I?
Monica: (giving Chandler a little hug) I don't think you'll ever get my parents that drunk!
Chandler: Ross, your parents like me, right?
Ross: Yes, of course they like you.
Chandler: Well, Monica just told me that they don't.
Ross: Yeah, they don't like you.
Chandler: (about Ross's parents not liking him) Do you know why?
Ross: Maybe it's because you're really sarcastic or maybe it's 'cause you, uh--
Chandler: Well, if people don't know, they shouldn't just guess!
Chandler: This is great! ...another Thanksgiving with nothing to give thanks for.
Joey: (absorbed in a video game) Maybe I give thanks for you shuttin' up, huh?
Chandler: Maybe I give thanks by taking my Playstation over to my new apartment.
Joey: Well, maybe I love ya.
Joey: (to Ross) How you got three women to marry you, I'll never know.
Rachel: (pleased with herself) Hey, Mon, look... I'm meltin' butter!
Monica: That's great, Rach'... You now have the cooking skills of a hot day.
Rachel: (to Monica) Technical question... How do you know when the butter is done?
Monica: (checking the saucepan) Well, it's done about two minutes before it looks like that.
Phoebe: He used to be just, "Jack Geller... Monica and Ross's Dad"... and now he's, "Jack Geller! Dream hunk!"
Rachel: I dunno, y'know, to me he'll always be, "Jack Geller... walks in while you're changing".
Chandler: (trying to butter-up Jack) Ross sure is a great guy. Y'know, I've always felt that how a young man turns out is a reflection... on his father.
Jack: I always thought that, too. Tell me, what does your father do?
Chandler: (reluctantly) He's a headliner of a... gay burlesque show.
Ross: Beef in a dessert? No, no, no. There is no way.
Joey: I know. And only one layer of jam? What is up with that?
(Ross flips through the pages of the cookbook)
Ross: Oh, my God. The pages are stuck together.
Ross: Oh, my God. She made half an English trifle and... half a shepherd's pie!
Rachel: (coming back from Joey's apartment) Joey... God, your apartment is like, a hundred degrees!
Joey: Did it make you wanna walk around in your underwear?
Joey: (frustrated, heads for his apartment) Still not hot enough!
Chandler: What about all that "friends forever" stuff...?
Ross: I dunno... I was all high.
Ross: Alright, I'll tell them it wasn't Chandler who got high... Now, who should I say it was?
Monica: You! It's not like it's a big deal... you don't still do it or anything.
Ross: Right... Now, who should I say tricked me into doing it?
Joey: (to Rachel) Will you hurry up! Did you not hear me before when I told you that all of Janine's friends are dancers? Huh? ...and they're gonna be drinking... a lot?!
Rachel: No, I did, but tell me again, because it's so romantic.
Joey: (about the trifle) Now, if anyone needs help pretending to like it, I learned some things in acting class. Try rubbing your stomach, or saying, "Mmmmm"... Oh! And smiling...
Chandler: Yeah, I'm not gonna pay for those acting classes anymore.
Ross: (after eating Rachel's trifle) It tastes like feet!
Joey: I like it!
Ross: Are you kidding?!
Joey: What's not to like? Custard... good! Jam... good! Meat... goood!!
Phoebe: (about Jack) I dreamt that we were going to get married, and he left because he had to go fight a fire. And, um, so, okay, I went to a nightclub, and I saw him making out with a girl.
Rachel: Oh my God, he dream-cheated on you!
Ross: Mom, Dad... You remember that time you walked in my room and smelled marijuana?
Jack & Judy: (looking at Chandler) Yes.
Ross: Well, I told you it was Chandler who was smoking... the pot. It was me. I'm sorry.
Judy: (disbelieving) It was you?
Monica: And Dad... Chandler didn't melt your records... Ross did.
Jack: (turning to Ross) Is that true...?
Monica: And Dad... You know that mailman that you got fired? He didn't steal your Playboys! Ross did!
Ross: (feeling cornered) Yeah, well, Hurricane Gloria didn't break the porch swing, Monica did!
Monica: (raising her voice) Ross hasn't worked at the museum for a year!
Ross: (shouting) Monica and Chandler are living together!
Monica: (screaming) Ross married Rachel in Vegas! And got divorced! Again!!
Phoebe: (not to be outdone) I love Jacques Cousteau!
Rachel: (paging through the cookbook) I wasn't supposed to put beef in the trifle!
Joey: (bellowing) I wanna go!
Judy: (barely collecting herself) That's a lot of information to get in thirty seconds.
Judy: Ross, drugs? Divorced? Again?
Jack: What happened, son?
Ross: I, I uh... I got tricked into all those things.
(After all of Monica and Ross's dark secrets have been revealed)
Judy: (seeing Chandler with new eyes) Chandler! You've been Ross's best friend all these years... stuck by him during the drug problems... and now you've taken on Monica as well... Well! I don't know what to say... You're a wonderful human being!
Chandler: (surprised and delighted) Thank-you!
Jack: Noooo! Thank youuuu! (hugs him, then turns) ...and Monica... and Ross... I don't know what I'm going to do about the two of you.
(Monica and Ross hang their heads, sheepishly)
Chandler: (as Jack and Judy's new hero) I'll talk to them...
Rachel: You guys... it was bananas, cream and beef! I just cannot believe that you ate that so that I wouldn't feel bad.
Monica: Well, actually, I didn't eat mine. It's still in the bathroom.
Joey: No it isn't, I ate that.
Judy: And we left ours in Monica's bedroom.
Joey: Nope, got it (points to Jack) ...and got yours too!
Rachel: Chandler? Are you gonna stick with that "bird" story...?
