In a last ditch effort to save the series several cast member changes were made. Lt Anderson and T.J. Wiley are now gone and replaced by an supposedly underage Lt. Jeb Pruitt, presumably to appeal to a younger audience. In addition, several nurses joined the cast and were given the name of "Pappy's Lambs", presumably in response to the then popular Charlie's Angels.
It was not unheard of for underage men to enlist and serve. The youngest man known to serve was 12 years old and won awards for service in the Navy.
The title refers to the forbidden fruit on the tree of knowledge that was placed in the Garden of Eden. Adam and Eve ate from the tree and were banished from paradise according the book of Genesis.
