You probably already know that my phone (G1) rocks, those who don't now you do. 
Anyway, the app store on it is not only full of useful apps, but also a bunch of "novelty" apps like fart machines and rim shots. However, there is one novelty app that I have fallen in love with and use so frequently I must share. It is called TWSS and does nothing more than deliver a wonderful string of words when pressed. In the right hands (mine) this app is an amazing tool (TWSS) and a perfect accompaniment to almost any situation. See the video below.
