In the scene where Roberta gets pulled out of the water & says, "well it's good to know who your true friends are" & then Chrissy punches her in the face & the camera shoots over in front on Roberta's face if you look down towards the bottom of the screen you can clearly see a white towel wrapped around her waist & there is also one one on the other girl's waist. How could they be carrying towels if they all just came out of the water pulling Roberta onto land?!? Probably because they were trying to dry the girls off before the next scene was shot.
