The One With All The Kissing - S5-E2
Corrected entry: When Monica and Chandler are in the bath, she goes under the water as Joey comes in, and when she reappears her wine glass is still full of wine. It would have filled up with water, not stayed with just wine. (00:00:55)
The One With All The Kissing - S5-E2
Corrected entry: When Rachel is getting rid of her date to go inside and console a depressed Ross, you can see a crew member just as she opens the door when she goes back inside. That's neither Chandler nor Joey since Ross was just sitting there alone.
Correction: There is no-one else there, except Ross in the background. What you see is maybe his shirt, but nothing else.
Correction: When Monica surfaces, it is actually Chandler's glass which is in shot and has never been underwater. Monica's glass isn't seen again.
