I thought the New Yorkers were funny (to be laughed at!) but it also shows you that despite what they like to make out they are not the friendliest people in the world. Some of them immediatley returned threats and intimidation to a greeting (though admitedly it was over friendly).
Jews wouldn't be friendly they love having a good laugh at themselves something which a lot of people everywhere should learn.
I think one of my favourite bits was the bear in the ice cream van, though it was scripted was very funny!
