I am simultaneously in awe and horror
This kid got skills. On the one hand, I bow to his multitasking mastery of being able to play Dance Dance Revolution whilst juggling three pins. I mean, I can't even juggle pins, or even juggle anything and dance at the same time. On the other hand, however, it is quite shocking to know the lengths that some people will go to perfect what is essentially, a parlour trick. This isn't even a trick you can do anywhere, since you need the DDR machine.
Still, definitely worth watching for the novelty.
