Other mistake: At Paul's wedding, Paul gives a speech saying that Connor was always there for him, "ever since our parents died when I was 2 and Connor was 7". However, in the scene showing when Connor and Jenny were just kids and she gives him a camera for his birthday, Jenny and Connor appear to be at least 10 years old - certainly not 7. Connor tells his ghost, "that was the summer before my parents died". The scene that follows shows the parents funeral, with Paul sitting next to Connor, and Paul appears to be about 5 or 6 years old - but much older than 2.nannykins
Continuity mistake: After the cake is destroyed Jenny is attempting to fix it. As she and Brad are talking, the camera switches angles viewing Jenny from the front and side. In the shot facing her, her hands are covered in cake icing, but in the side view there is little to no cake icing. It is continuous throughout the scene. (01:06:25)
Uncle Wayne: So here's a couple of tips. When you first meet a girl you give her two compliments above the neck. Yeah, tell her she's got nice lips, nice eyes, nice hair... She's intelligent, her moral ethics, whatever crap comes to your mind. Then just when she begins to thinks that you're another - you know - vanilla nice guy that she can tool around with all night without getting naked...you *insult* her! Flip the power dynamic and your let her know that you're here to play.
