This happend several years ago and its still the funniest thing that ever happened, imo, in my humble honest opinion, to be honest:

Once upon a time, a YOSPOSTER found a fake keygen that forced computers running it into a botnet. This botnet was incredibly poorly written and lacked any of the security/encryption that pro botnets feature. After a few hours of analysis, the YOSPOSTER found that he could easily take control of the botnet and push new payloads to all of it's members. Thus, a program was concocted that opened a window on the screen with a picture of Bill Cosby, took a screenshot, and uploaded the screenshot to a web site. This "cozpop" executable was pushed to all the computers in the botnet. What you have seen is a screenshot from one of these infected computers.
