Continuity mistake: Sometimes Ed's fireplace in his office is on the right wall but then other times it's on the left. Plus Ed and Mikes' offices switch sides mid series. Ed's office is stage right in early years, Mike's is stage right in later years.
Continuity mistake: In the opening scene, Mike is cooking bacon on a gas stove. He is talking to Vanessa and is seen to shut off the gas under the frying pan. The scene cuts to Vanessa and then back to Mike. The gas under the pan is suddenly back on.
Answer: It looks like it was just a set change. They switched what side of the set the offices are on.
