In the scene where Brian, Rachel, Riley and Dylan (if that's how you spell it) are at the tea party/polo game the part where they show Dylan asking about the tea sandwiches. If you look at Brian's tea cup it switches hands. it starts out in left hand. then it goes to Dylan. when it goes back it's in Brian's right hand. it goes away and then when it comes back to Brian it's back to his left hand. the moves are too quick for him to be able to switch hands.
