None — A video posted to popular video website YouTube Thursday shows a bird taking several trips down a snowy metal roof while riding a small plastic donut-shaped device.
The crow takes three trips down the roof before flying away from the area with its 'sled' firmly in its beak.
The video, apparently narrated by a Russian-speaking family, is slowly gaining traction on the web and was recently picked up on reddit.com, the so-called front page of the internet.
