Cowsay will turn text into happy ASCII cows, with speech (or thought) balloons.
If you don't like cows, ASCII art is available to replace it with some other creatures (Tux, the BSD daemon, dragons, and a plethora of animals, from a turkey to an elephant in a snake).
Port of the original command line application "cowsay", made by some FIXME.CH hackerspace members during 28C3 in Berlin.
