I have no idea where my nephew Richard comes up with such things, but the two minute video that he links to in this blog post is pretty darn clever.
By the way, Rich, I highly recommend that you do not attempt to perfect the skill evidenced in the video while juggling your distractions this fall at Northwestern University Law School. Not that it would interfere with your studies that much. Rather, too many professors would be pestering you to teach them how to do it! ;^)
