The One with the Fake Monica - S1-E21
Corrected entry: After Ross chides Marcel for humping the lamp, in the next shot, you can see Marcel come out from the hallway leading to the closet. He was obviously released from back there by the handlers for that particular shot. (00:00:40)
Correction: Marcel manages to move the lamp to by there and could easaly have gone up there before coming out to Ross and the gang.
