Google is suing sex-orientated look-alike Booble for copying its overall look and style, despite the fact that the pornography search engine makes plain its intent to be a joke and not a serious imitator.

Boobles defence is that it is a parody of Google, which it is technically free to do under the first amendment. "The entire universe gets the joke. Only a lawyer could say 'Booble' without smiling," said a Booble representative.

Google retorts: "For a work to constitute a parody, it must use some elements of a prior author's composition to create a new one that, at least in part, comments on the original author's works."
