Ran Ran Ru

Ran Ran Ru, or Donald no Uwasa, was a series of McDonald's commercials in Japan ran from 2004 to 2007, and a series of secondary creation by netizens based on those commercials.

Translated to "Donald's Rumors," Donald no Uwasa asked questions about Ronald McDonald like "How long are Donald's shoes?" and the answers were available on McDonald's website. One of these ads asked, "What what what is Ran Ran Ru?" and the answer was: "Ran ran ru! When Donald gets happy, he just has to do this. Let's do it together, everyone! Ready? Ran ran ru!" This ad got remixed with "U.N. Owen was Her?" from Touhou Koumakyou ~ The Embodiment of Scarlet Devil by a netizen and became a meme.Santa clause hohohohohohho
