Jack Black’s Octagon refers to a clip taken from a 2008 episode of Sesame Street[1] in which Elmo teams up with American singer and actor Jack Black[2] to define the word “octagon.” Black’s strange demeanor throughout the skit has led it to become common source material in YouTube Poop Music Videos as well as MAD video remixes.


Jack Black’s Word of the Day skit was first uploaded to Sesame Street’s official YouTube channel on July 18th, 2008 as a teaser for the 4161th episode of the children’s show which premiered on digital cable television channel PBS Kids Sprout on August 11th, 2008. As of February 2013, the YouTube video has been vieweed more than 5.7 million times.


The first parody video using this source material was uploaded to YouTube on November 24th, 2008 by warmandcrispy.[3] Entitled “Jack Black defines orgasm,” this video has nearly 6000 views as of February 2013. Throughout 2009, additional YouTube Poop remixes were uploaded with the snowclone title “Jack Black Defines X”, which has more than 170 search results on YouTube[8] as of February 2013.

These parody videos saw an increase in popularity after the well-known YTPMV creator MatrixMarioX[4] posted the video “Octagons have ⑨ Sides”[5] in January 2010. This music video also featured the song “Beloved Tomboyish Daughter” from the Touhou Project. As of February 2013, more than 800 videos related to the keywords “Jack Black Octagon” have been uploaded to YouTube.[6] The series also took off on Nico Nico Douga in late January 2010, after someone reuploaded MatrixMarioX’s video[9] and nearly 100 other remixes[7] have been uploaded as of February 2013.
