Plot hole: Dora is sleeping after being taken to the hospital, she wakes up in Paul's bed. Assuming, she recognizes the place as the one where the fundraiser/party is held, how can she know that it was Paul's bed and that he lived there? Furthermore, she also seems to know that she was in the hospital, and that Paul was the one who took her. Seeing the exchange of dialouge between Paul and the doctor, and Paul and her, there was no way she could have known that information prior to her waking up.

Factual error: When Paul goes to rent a movie, his first words to (David Spade) are about what movie to rent. When (David Spade) vetoes both of Paul's choices, he offers him a third, which Paul accepts and then leaves. Not once did (David Spade) ask for an ID or video rental card. He didn't even check the movie out of the store's inventory.
