Duck, Duck, Goose

I see lots of weird stuff in Manhattan, but this morning I was walking down the street and there was a large black man making duck calls on the street. I'm not exactly sure what ducks he was calling, considering it's winter, and we are in Manhattan. I thought maybe it was like Batman, and the Duckmobile was going to drive up, but if it did, I missed it. THAT would have been cool, though.
