The One With Joey's Big Break - S5-E22
Factual error: Joey and Chandler are supposedly crossing the George Washington Bridge but the exterior background viewed from inside the car is very obviously a repeat reel of another bridge, and their conversation goes on for far too long for the actual crossing. And the cutaway shot after Chandler is kicked out of the car shows an aerial view of the Brooklyn Bridge.

Continuity mistake: When Joey arrives in the desert there is a lot of stuff not in vans. As the director gets into his car, loads of equipment is still in the desert, but a few shots later the vans are full and leaving. (00:18:50)

Other mistake: When Joey and Chandler are in the cab on the bridge, Joey quickly stops the cab so Chandler can get out. However, on the screen behind, the background doesn't 'slow down' as Joey does, it just continues as if the cab is going at the same speed. Then, in the next shot, it is still. When Joey sets off again, the background stays the same and doesn't show that the cab is getting faster. (00:13:05)

Continuity mistake: When Rachel knocks over the cereal its position changes between shots. (00:04:15)

Factual error: In the scene where Joey is supposedly in the Nevada desert, Saquaro cacti are seen in the background indicating that the scene was shot in Arizona or Mexico.

Other mistake: When Ross is questioning Phoebe on why she is mad at him, he has his blue sweater on backwards.
Suggested correction: So he has his sweater on backwards. That's a character mistake, not a movie mistake.
