Microsoft’s Windows Phone 8.1 update was released only yesterday, but Cortana users have already discovered a number of funny responses from Microsoft's new personal digital assistant. The best Easter egg is the return of Clippy, Microsoft’s assistant from Office. While Clippy doesn’t fully replace Cortana, he will show up temporarily if you ask "do you like Clippy?"

Other "chit chat" responses include "do you like Steve Ballmer?" to receive a developers, developers, developers reference, or "do you like Satya Nadella?" to get Cortana’s take on Microsoft’s new CEO. Cortana will also respond to "tell me a story" or "tell me a joke" with equally witty responses. "What’s the best phone?" provides one of the more Halo-like responses. Cortana is part of the Windows Phone 8.1 update which is now available for developers to download and install.
