Scooby Werkstatt, aka Scooby1961, aka "natty king of /fit/," was a gay, JewishYouTube fitness trainer who made vids for teens with exercises to "get fit" with. Sometime between 2012 and 2013, he began posting on 4chan's /fit/ board and quickly rose to /fit/ meme and celebrity tripfag status.
Unfortunately for both Scooby and /fit/ though, this was not to last.
