[Addams Family] Gosh... So many questions. What is Thing and how does he drive cars and do other things? What is It? How does the family not die when they ought to?

For example when they drink poison, get shocked by a radio in a bathtub or have an explosion happen less than a meter away from them? 

Why feed the baby a raw egg & vodka?

Thing is something too horrible to be seen, except for his one human arm. He didn't become a disembodied hand until the movies, at which point we have to assume magic is involved. 

Cousin Itt is just an exceptionally hairy person with a strange voice. At least, the family insists he is, and if anyone asks him what's under all that hair he says is "Roots."
