God that brings back memories. When I was about 20 I lived in a condo that had about a two acre lake in the middle of them with several pairs of swans. I was out walking with the girlfriend around the lake when apparently one of the swans thought I looks tasty. It came at me like there was no tomorrow. I remember kicking it out of fear, as I couldn't imagine a bird attacking a human, but it did.
Apparently it was a draw, the swan left me alone and I escaped with only my pride damaged.
Was funny when I look back on it.
