Starring Sandra Bullock and Ryan Reynolds and Rose from the Golden girls (I'm not sure of her real name).
This movie is very funny. It's about this woman who is going to get deported back to Canada but then thinks of an idea of marrying her assistant. They both go to his parents house and announce the engagement and all the time lying about getting married. I won't ruin it for you by telling you everything but I do highly recommend it. It's very funny.
