You know your kid is a New Yorker when...

He pretends to be a street performer.

As soon as he finished singing "Twinkle, Twinkle Little Star", while strumming the guitar, he told me to put money "in the case". I tossed in a quarter. He promptly said, "More please." I rewarded good manners with another quarter.

I have since collected two forgotten quarters off the floor.

As they say:

You can take a kid out of the city. But you can never take the city out of a kid.
