Oh yeah, I remembered another continuity thing from the first season to later seasons - Chandler referred Ross to his guy when he had that thing on his ass - Chandler’s guy sliced his third nipple right off for him, yet Chandler had it back on again in later episodes (like the one with the girl with the artificial leg). And then he had it off again in that episode.
Are you sure? I don’t think Mindy Sterling has been in Doctor Who, but I’d be curious to know when and are where, if she did.
“IT TASTES LIKE FEET!” Still our go-to line for my sister and I when we’re sampling each other’s cooking.
The birthday party when Monica’s parents didn’t know she was dating Richard, but only knew he was dating a “twenty year old Twinkie” had some of the best lines.
Jack Bing to Richard: I tell you what. Let’s trade. I’ll let you use my sports car and you–"
Ross (interupting)–Dad, I’m begging you. Do not finish that sentence.
Later, after Jack has found his signed bat and comes into the kitchen, where his wife his waiting to tell him about Monica and Richard
Jack: Found it.
Ross: I’ll take that for you.
He grabs the bat and walks out of the room. The look on Jack’s face is priceless.
I just watched the original break-up. Damn. That wasn’t funny at all. (For a sitcom, that was some damned fine acting. Actually, that was some damned fine acting, period.)
“Oh, dark mother, once again I suckle at your smoky teat.” Said by Gunther after he has a drag of Chandler’s cigarette. 
I think my favorite Friends episode is the one where the Joey and Chandler challenge Monica and Rachel to a trivia challenge about each other. TV Guide comes to Ms. Chanandaler Bong, that Chandler’s job title is not Transponster (which is also not even a word), and Monica has eleven categories of towels.
Are you sure that wasn’t Chandler speaking after taking a drag off Gunther’s cigarette? It’s not like anyone ever cared what happened to Gunther after he lost his soap-opera gig.
Checking YouTube, I find that the Cat was right and I was wrong.
And: Joey’s favorite food is sandwiches, Monica was “big fat goalie” when she played field hockey, and Rachel lies about her favorite movie.
Since I just watched it, I was pretty sure. 
I am still making a note of your insolence.
Another time was when Monica was developing recipies for “Mocklate” and the results were revolting, leading to Phoebe’s pained cry of “THIS IS HOW EVIL TASTES!”
That episode had one of my favorite exchanges. Tanning salon guy asks Ross what number he’d like to be.
Ross: I like the way you look. What are you?
Tanning guy: I’m Puerto Rican.
I just love the matter-of-fact delivery by the tanning salon guy.
oh, yeah, that’s a tough episode that hits really close to home. haven’t we all had that breakup, with someone you really, really loved, that took hours to finish? it still makes me tear up.
so yeah, i love friends. i love that after seeing each episode a jillion times there are still lines that make me laugh out loud. lots of them are ross lines, like the aforementioned “PIVOT!” and “it tastes like feet!” i also love when he and monica are going through their old things at their parents house and he says “ooh, my rock polisher!” it’s all in the delivery.
i agree about monica becoming shrill and annoying in the later seasons. like the episode where she thinks the maid is stealing her clothes, give me a break. that said, i really love that once she and chandler got together, they stayed together. it provided a nice balance for all the ross/rachel will they won’t they drama.
i also really love this scene (skip to about 2:00) when joey is trying to apologize for accidentally proposing to rachel and he goads ross to punch him. he finally does, joey ducks and ross hits a post instead, stumbles back to gunther who’s wearing a delighted grin. it really reminds me of the earlier seasons which had a lot more physical comedy.
Dark Online Fan Theory: Monica eating so much of the Mocklate is why she and Chandler were unable to conceive years later.
My continuity issue with Friends is when Ross and Rachel drift apart the first time, Ross is made to look foolish for being jealous because Mark has a fiance. The fiance is never mentioned again and a few episodes later Mark indeed is into Rachel.
She says it’s “Dangerous Liasons.”
It is, in fact, “Weekend at Bernie’s.”
Rick-that’s what I was refering to. 
BTW, don’t touch Ross’ food, especially his sandwich!
I thought Joey doesn’t share food!
I actually much prefer her reading of “But they don’t know that we know that they know…”, which is a simple line on the page but almost impossible to deliver correctly. (And then Matt LeBlanc’s exasperated sigh into his hands that the ruse was going to continue capped it off)
My all time favorite Friends moment is Phoebe and the bagpipes. Never, ever fails to make me laugh like a loon.
(Watch to the end to get the blooper version of the scene, too.)
