Accually, i noticed there were 2 aunt vivs becouse of Jazzy Jeff, "You know mrs. banks, ever since you had the baby, there is something diffrent about you!" that was awsome. but it took me a while to realize there were 2 houses!!! trouble was i came to america and started watching in '96 after the last episode, so all i saw were re-runs, so all of a sudden this one day it hit me, oh my god there are two houses... How did i miss that one!!!
