Nothing is more New York than Seinfeld May 19 2014

Beginning this week, the No. 7 train's interior and exterior will take on the decor of the “Seinfeld Diner” to celebrate the first Mets-Yankees Subway Series of this year's baseball season.

While that may not be big news for any other city, no town loves Jerry Seinfeld more than New York.

In 2002, TV Guide named Seinfeld the greatest television program of all time.

The "Seinfeld train" will be up for one month.
