A subway rider is wowing the web with his incredible puzzle-solving skills.
A video posted on Twitter shows the man, who is dressed in a Dragon Ball Z T-shirt, completing a Rubik's cube using just one hand at a time.
In fact, he is barely paying attention and appears to be transfixed by something else on his phone.
