Today by far is my favorite holiday. It's the one day that webmasters get to be creative and do things that normally wouldn't fit with their sites general themes. For example, Google attempts a high tech way of quenching peoples thirsts, Wikipedia sells out to Britannica, a RFC is written on Morality, and much much more!
