NEW YORK, UNITED STATES: New York Mayor Rudolph Giuliani wears a Baltimore Ravens team hat and tosses a knish during a press conference 31 January 2001 at City Hall in New York. - 

And this final note on supply and demand: Of Knishes.

The jewish doughy snack food generally filled with potatoes and other yummy things. It turns out that a fire at the country's largest knish-maker has created a nationwide shortage. Gabila's Knishes in Long Island usually sells about 15 million knishes a year.

The fire has meant a shortfall of knishes at supermarkets, stores and delis. Gabila's promises that they will soon replenish the knish supply.

Just in time for the start of Hanukkah.
