Wendy and Sandy are at band practice. Wendy is sitting center row, playing a trombone. Sandy is playing a triangle, sitting directly behind her, slightly elevated. He is intensely peeking downward. We get a brief shot from his POV, staring at Wendy's butt crack.
Greg falls off the high board into the pool, leaving his swimming shorts behind. He spends some time panicking in the pool until a pool attendant gives him some princess pants to put on.
