Penguin Slips on ice (YouTube.com)
(YouTube.com) -- You would think penguins could keep their balance on any type of surface, especially while walking in a group formation.
Well, some video of a penguin slipping on YouTube has gone viral (more than 1,000,000 views).
The penguin slips and falls, and the other penguins groan in disbelief.
When the penguin who fell down, gets up, it sounds like he/she shouts back at the group: "it's not funny!"
