Corrected entry: When Phoebe goes to visit her birth mother in Montauk, her mom says "I wish someone would've been there to tell me how terrible it is to give up babies". The scene cuts to a shot of Phoebe holding the puppy, revealing a side view of a stand-in, not the actress playing her mom.
Corrected entry: Chandler calls Monica to tell he's trapped in an ATM vestibule with Jill Goodacre on a mobile phone, however Monica answers by picking up the house phone. In a power blackout, the phone wouldn't have any power so Chandler shouldn't be able to reach Monica.
Corrected entry: When Joey and Chandler are ordering a pizza they tell the pizza place to send the food to apartment 20 which is Monica and Rachel's apartment but it is clear that Monica isn't home because she is catering and Rachel is on her date with Ross, so how do they get the pizza.
Corrected entry: When Chandler and Phoebe go to the jewelry store Phoebe's hair has two braids on each side that are being held together by what appears to be a hair pin, later on the scene where Phoebe is trying on a tiara she only has one braid on each side and no hair pins.
Corrected entry: When Phoebe and Chandler are about to kiss there is a bottle of wine and two glasses on the counter. It then cuts to a view of Phoebe with no bottle or glasses on the counter, just a phone, and then later in the same scene it cuts back to Phoebe again and there are two glasses and a bottle of wine again.
