A man, who calls himself Rubocubo, is making the Internet feel inadequate after appearing to solve three Rubik's cubes while juggling all of them.
Yes, that's right, he's juggling them.
If the video is real, the act is an impressive one.
Reddit user, demthunderchiefs, who claimed to know the unnamed man wrote: "I actually know the guy in that video, he very well may have an IQ of 180.
"Dude's incredibly smart."
However, other Redditors suggested the footage was altered.
mmmph0 writes: "Um, yeh, aside from the more obvious fact that he doesn't manipulate his hands/fingers in any way that would actually twist the cubes to rotate the pieces.
"Just palms them. Not played in reverse, someone just clearly CGI'd the colours."
Others sceptics also suggested that "he could have been simply scrambling them as he was juggling them and played the video in reverse which is a lot less impressive.
Stay classy, Internet.
