Pigs on Bicycles?

Yesterday Bismark (my trusted driver, and a close friend here in Nicaragua) points to my window and says "look!" with a huge grin on his face.

A man was riding a bike with a metal basket attached to the front (fairly close to the ground). Sitting in the basket were two full sized pigs, nose in the air fully enjoying the ride.

Bismark and I both got a good laugh at it.

Then he turned to me. "Do people drive pigs around on bicycles in New York City?"

I couldn't even begin to explain...
