The name Funke, and the fact that Rhett is a Never-nude, are references to the cult hit "Arrested Development" character Tobias Funke, one of whose defining characteristics is the fact that he is a Never-nude.
Rhett is actually supposed to be an adult,[citation needed] not a young adult, and in 13 days he is supposed to age into an elder. This can easily be fixed, though, by triggering an age transition either by using a birthday cake or using the cheat testingcheatsenabled on him. Prematurely aging him will still make younger than his wife, Sabrina Funke, even though he is supposed to be four days older than her (she has 17 days to go until she turns into an elder).
