Other mistake: When the plastic surgeon is giving Samantha a breast exam, you can tell that he isn't really examining her breast. He is actually moving his hand in a circular motion in the air above her breast pretending to give her an exam, but is touching her hospital gown instead. (00:20:20)
Other mistake: At Steve and Miranda's wedding, Charlotte is holding baby Brady, who looks younger than a year (around 8 months) and is using a pacifier. But in 2 episodes prior, they celebrated Brady's 1st birthday and the actor who played Brady looked way older than the Brady at the wedding. I know they cast different kids, but it seemed as if Brady aged backwards.
Answer: Yes, it is.
