Corrected entry: When George Clooney answers the phone (while Monica and Rachel are pretending to be each other), he starts handing the phone to Rachel, saying "Rachel, it's your dad", but should be passing it to Monica (as he thinks her name's Rachel). The angle then changes, and now he's handing it to Monica.Jon Sandys
Corrected entry: When Monica is filling out Rachel's medical information, she has to change the name on the form so Rachel can use her insurance. You can see that she has a pencil in her hand. However, she goes up to the desk to get a new form. It makes no sense that she would arouse suspicion when all she had to do was erase Rachel's name and put hers.
