1. Think of a word or a phrase that you would use to describe me. 2. Go to Google Image Search (or your preferred inferior search engine) and search for that word. 3. Select the picture you see as the most fitting, and post it or a link as a reply. 4. Do whatever you want to do next.
chebutykin posted a while back about a giant centi/millipede and posted a picture. Someone commented with a link to a giant spider post on Somethingawful.com (I think). "Put the clock back." was the refrain from that post.
