Plot hole: When Clooney gets the call from Melanie's mother, he calls Melanie to let her know that her mother can not watch her son. She asks how he got her phone number, implying that she did not know that the phones were switched. Right afterwards she tells him he has a meeting at five. How did she know that he had a meeting if she just found out that they switched phones?
