Du's Law 

Du's Law is similar to Godwins Law in some respects. Du's Law is an assertion that has become an Internet adage. It states: "As an online discussion grows longer, so does the probability of a reference to Wikipedia. In other words, Du said that, given enough time, in any online discussion—regardless of topic or scope—someone inevitably makes reference to Wikipedia. The calling of Du's Law immediately ends the argument.

<person_one>My point is totally valid! <insert wikipedia reference>
<person_two>I site Du's Law, thus winning this arguement.
