The One With The Truth About London - S7-E16
Corrected entry: When Monica and Chandler are taking their clothes off, Chandler takes his clothes off really fast, and Monica says "wow, you're fast". Then they say that they are about to see each other naked. Monica isn't wearing the top of her dress (a two-piece) any more, but she could only have removed that by pulling it over her head, which she hasn't done.
Correction: The mistake states, "Monica isn't wearing the top of her dress (a two-piece) any more, but she could only have removed that by pulling it over her head, which she hasn't done." This is incorrect. Yes, Monica is wearing a 2-piece outfit, but her sleeveless fitted top has a zipper at the back (down to the hem), and it's removed by her reaching behind and unzipping the back so it's off in a flash. It is not removed by pulling it over the head.
