Inspired by this post by @fossilesque@mander.xyz, @LibertyLizard@slrpnk.net proposed to turn that neat idea into a challenge series. It's not my idea, so feel free to post your own challenges here or in whatever community you find appropriate.
Now back to the game - let's see who'll be the fastest nutter of the day! ;)
Warning: The challenge has been solved already, so don't check the comments if you want to avoid spoilers.
Not a nut
