Everything you didn't know about the pancake on the head bunny.
n July 2002, a definition entry for the rabbit was added to the online writing community Everything2[14] and the next year, Oolong’s page was mentioned in a New York Times article[15] about the rising trend of photo bloggers. By 2007, the dismissive phrase “so here’s a picture of a bunny with a pancake on his head” began appearing with photos of Oolong[6], which have been used on discussion forums and image boards to denote confusion, as in “that was nonsense what you just said there, so here is some more nonsense.” The phrase was later used by American humor magazine Mental Floss[5] as the title of an article about the rabbit’s life. Photos of Oolong have also been featured on the Telegraph[4], Urlesque[16] and Metro.[17] In early 2010, two Facebook fan pages[18][3] were created for the rabbit, with approximately 3500 likes between them as of October 2012.
