Every time Liam's family went on vacation, Jay Rosen would always ask Adam to water their flowers while they were gone.
Liam would always go over to Adam's House and tell him that Jay wanted to show him how to water the plants. Adam recalls that he was always inexplicably playing Zelda: The Ocarina of Time when this happened. Jay would then spend 30 minutes telling Adam every intricate detail about how to water plants.
One time, Marcus and Adam decided to pee on one of Liam's plants, and it later died.
