Subject: test to see if a variable exists

So I am stealing all these identities and storing everything in a big
array of objects stolen_identity, and having the index be social
security numbers:

ss[34323843] = Stolen_identity.new

But say I pick up a paycheck stub and it has 3428294. How do I know if
I already have it? Does
   if (exist ss[3428294]) then ... end
work? How can I see if a variable exists?

Thanks.

(please include your social security with your answer)

ss[34323843].nil?

my ss# is 1123581321
