The phrase "there's no place like 127.0.0.1" is a play on the famous line from the movie "The Wizard of Oz" where Dorothy clicks her heels together and says "there's no place like home". In computer networking, 127.0.0.1 is the IP address assigned to the "loopback" or "localhost" network interface. This means that when a computer sends data to 127.0.0.1, it is actually sending the data to itself.
Therefore, the phrase "there's no place like 127.0.0.1" is often used by computer programmers and IT professionals to express the idea that there is no place like home, or in this case, the computer that they are currently working on. It can also be interpreted to mean that a person is most comfortable and productive when working on their own machine, in their own environment. The Wizard has a t-shirt with this on it because, well... I'm a geek! You will also see this along the left side of 'OZ' - clicking on the 'OZ' logo will take you to the newest post -- home!
