People think oh, there are millions of people in New York, so it must be really easy to meet someone.
This seems true until we begin ruling out large numbers of people:

Those of the other gender
Those who are too old/too young
Those of the wrong sexual orientation (read: this is NYC, subtract 50% of current number)
Those with significant other(s)
Those with criminal records
Those in professions that smell like meat (street vendors, butchers, etc.)
Those who would stab people over the Yankees
and Mouthbreathers.

According to my calculations, there are approximately 12 legitimate prospects somewhere in this city.
