Just curious: why is the search engine called Duck Duck Go? Any reasons to the name?

Update: found on Wikipedia - Some reporters have called the Duck Duck Go name silly or inappropriate for a search engine. When questioned about the name, founder Gabriel Weinberg has explained, "really it just popped in my head one day and I just liked it. It is certainly influenced/derived from Duck Duck Goose, but other than that there is no relation, e.g. a metaphor." The company's FAQ says something similar
