Duck on leash seen waddling around subway car

NEW YORK -- It's not a sight you see often - several straphangers in Brooklyn were treated to a duck on a leash.

Maximillian Kirchoff, who posted the video on social media, says he was on the G train in Williamsburg when suddenly he began hearing loud quacking.

The duck can be seen waddling around in the subway car.

According to the Department of Health, keeping a duck is illegal in New York City.
