When two 12 year-old girls attacked their friend in the woods of Waukesha, Wisconsin in May of 2014, they claimed to have done it to please Slender Man -- a fictional monster created by Eric Knudsen, A.K.A.

That incident put a mainstream, national news spotlight on the figure, which was already being widely circulated and adapted online as a meme.

In this bonus episode of Endless Thread's meme series, we examine Slender Man as monster, meme, and myth.
