Re: You were talking about goatse-ing, right?
I was indeed talking about goatse-ing; although that is kind of the lazy option; and has the additional problem that the "replacement" image will be squished to the dimensions of the hotlinked image...thereby diminishing the glory somewhat in extreme cases. The true craftsman will, of course, personalise their replacement image. At the time, it was a magnificent way of spending the couple of hours after returning from the pub.
