In the movie a kid wants to date this girl and he thinks it's a good idea to sit in her yard all summer to try and when here affections. He has a friend that has sex with a water melon and later has his penis shocked by a sex toy. The girl has a boyfriend who stuffs his pants. Other details I remember are that the girl has small breasts that he believes won't sag as she ages. The friend who has sex with the watermelon thinks or maybe just wonders if men only have so many erections in their lives and it's possible to run out of erections.
