Apple's voice-recognition technology, Siri, has been lauded for its groundbreaking ability to understand natural human language rather than just simple commands. In the past, most people have used it for various mundane activities -- finding the nearest sushi restaurant or theater showtimes for a movie, for example.
In its most recent incarnation, you can even ask it questions ("Will it rain today?") and it'll use GPS to spit out an accurate answer. But some creative folks have tested Siri's abilities on the new iPhone 4S with rather amusing results.
