At approximately 34 minutes into the movie, when Brooke and Ryan go bowling, and after Ryan gives Brooke a quick lesson on proper bowling technique, Brooke then rolls a strike. In their excitement, Ryan picks Brooke up and twirls her round in a circle. When the camera pans down the lane where Brooke just knocked down all the pins and the pinsetter should be going through its cycle, you can see the pins are already set in an upright position.
