5. Sabre being pronounced "saber" when it obviously makes more sense to pronounce it "sab-re."

This one really isn't an error it just really bothers me for some reason. It just doesn't look right.

6. Andy talking on the phone.

Big error for this one and I can't believe I caught this one too! Season 6 episode 20, Andy is on the phone with a potential client and he walks into Darryl's office looking for a pen. When he first says then clients name he says "Eddy" and the next time he says the clients name he says "Teddy" so is it really Eddy or Teddy??

Also in Season 6 Andy is talking to the camera crew briefly mentioning that he has a stepdad. There was no mention of his stepdad in earlier seasons in fact his parents are still married in later seasons so where did his stepdad come from?
