(CNN) -- By now, early adopters of the iPhone 4S, which has sold more than 4 million units since debuting on Friday, have no doubt taken Siri for a spin. The voice-activated "personal assistant" is a talkative tool that helps schedule appointments, send and receive messages and perform any number of other routine tasks.

The Internet, always up for a chuckle, has noticed. Blog posts, tweets and even whole websites are popping up to share what happens when users start testing the boundaries of the app by peppering Siri with off-the-wall questions.Siri is the voice-activated personal assistant app on the new iPhone 4SBesides performing routine functions, Siri offers humorous responses to certain questions"What is the meaning of life?" produces several different answersSiri also is ready for "2001" and "Star Trek"-related questions
