Google has just enabled no-click voice search in its latest Chrome update. Now anybody can search without typing. Just open a new Chrome tab and say "OK Google" (after enabling the feature in the Privacy settings). Once this catches on, you won't look nearly like such a lunatic.
Note: If you want it to even have a hope of working, you do need to set your default search engine as google.com, and the language English (US). (Thanks Trolly)
