I'm a Giraffe

This was quote of the day on my Google home page:

"I know who I am. No one else knows who I am. If I was a giraffe, and someone said I was a snake, I'd think, no, actually I'm a giraffe."
- Richard Gere

What is this supposed to mean? It's funny. And it may have some philosophical import. Any comments?

Do unicorns exist?

Do unicorns exist? If so, what are they? If not... what are they?
