About two years ago, I found this movie one movie that I liked. I only remember one scene though. From what I remember was that there were girls and one guy rolling up to beach in a Jeep (I think). The two girls get out and strip naked and run into the water. The guy does the same thing. Once all three are in the water the girls run put their clothes back but hide the guys clothes in the sand and force him drive with only a poster to cover him.

Does anyone know the movie that I am talking about or did I just think of this in my head. If it helps I think the movie was from the 80s.
