This was the fourth [[:Category:April fools' comics|April fools' comic]] released by [[Randall]]. This comic isn't a static image - even the title text changes depending on which part of the image you're hovering over. It presented a competition for students to see who could come closest to breaking a {{w|Skein (hash function)|Skein hash}} but also an aid appeal for the Wikimedia Foundation.

This comic isn't a static image - even the title text changes depending on which part of the image you're hovering over. The blank regions in the above image are dynamically generated from various sources.
−
The comic references multiple times {{w|Baidu}}, a large Chinese Internet services company. Baidu controls the predominant Internet search provider of China and is sometimes called the "Google of China" for the similar services it provides. Baidu Search results follow the censorship dictates of the Chinese authorities, causing it to return censored responses to searches for politically sensitive terms when executed by web browsers in China. Megan's reply "But nothing about Tiananmen Square." in the first panel is a reference to the {{w|1989 Tiananmen Square protests and massacre}} that killed hundreds of civillians. "It takes great minds to stifle other great minds." and "Let's block Canada" in the second panel are also references to the arbitrary government censorship of Baidu and other Chinese companies

On this page, users were invited to enter "Your school's domain name" — presumably intended to be their college alma mater. (At least in the beginning, only a few top-level domains were accepted.) If the user entered an acceptable domain (by xkcd's rules, which apparently changed during the 48 hours of the competition), they could then enter data values one at a time. For each data value entered, xkcd returned a hash value and the number of bits by which it differed from the target value. The object was to achieve the lowest possible number of differing bits, ideally zero.

A ranking page showed the lowest value achieved for each domain name entered, but not the data that achieved it. The first name on the list was substituted in various panels, and the third-place school showed in panel five. No data values were reported by xkcd, but various results were posted by users of the xkcd forums and on other websites, leading to copycat submissions, so that occasionally large numbers of institutions would show the same moderately low value.

|University of Michigan is in Ann Arbor; the mascot is the Wolverine. "South Detroit" is referenced in the song {{w|Don't Stop Believin'}}, which is notable because there is actually no such city or neighborhood; rather, Detroit is one of the only places in the contiguous United States where you can drive south and wind up in Canada, namely in the city of {{w|Windsor, Ontario}}. Michiganders therefore often object to the bad geography in the song.
