Continuity mistake: Ross, Joey and Chandler are in Chandler and Joey's appartment talking about Ross' decision. Chandler has a green bottle in his hand. He puts it down behind the computer by the microwave, but when Ross starts listing Rachel's "cons" the bottle's suddenly at the opposite end of the counter. (00:07:40 - 00:08:25)
Continuity mistake: When Monica goes to the mockolate interview, at one point she says "abso...lutely." While she is saying this, the mockolate packet is in her hands, but when the shot changes, the packet is on the table. (00:06:10)
Continuity mistake: At the very end when U2 are on the radio it shows Rachel picking up the phone to ring the radio station. Without the song skipping it cuts to Ross and straight away the DJ comes on and says that Rachel rang her and told her what Ross did.
