When you start to type a query, Google suggests popular search terms that include your keywords. Sometimes the suggestions are surprising, especially when the suggested queries are long and descriptive. A suggestion like [i was bitten by a turtle when i was a young lad should i still drink orange juice] might surprise you if you didn't know that it was a question on Yahoo Answers that became famous.
Other suggestions could be popular songs, movie quotes or Internet memes. For example, [Dinosaurs were made up by the CIA to discourage time travel] is the name of a song.
The two examples are from Autocomplete Me, a site that collects funny Google suggestions and lets you rate them.
