/prog/ challenge #214

/g/ garbage can
Ever had a garbage sentence pop into your mind, that you just had to dump on /g/? Well, this program will allow you to do that without being exposed to all the crap you find on that website.

Write a program that reads a message from its input and posts it to a random thread in /g/. The captcha can be downloaded and displayed by an image viewer, then filled out by the user.

What is this /g/ that you constantly speak of? Is it on 4chan? Or if not, where?
