Great video I was though very very disappointed that he didn't do the funny face at the very end that he did on his last video on Snotr (can't remember what it was about now) I never in my imagination thought it clicked like that.

When I was 5 or 6 years old I broke my first retractable pen, and that is when I discovered what a simple yet genius marvel it was. The fact that it's simple is probably one of the reasons it took 66 people to design it, sometime what's in plain sight is most difficult to see.
