How to tell a good camera from a bad one

Wanna share this great film I saw last night.. Probably one of Japan's most prolific inventor; he has a very special way of telling a good camera from a bad one.. Shuffle along to 1:45 :D

p.s. A word of caution.. if you intend to use Dr. Nakamatsu's method of determining if our club's cameras are good or not.. Please make sure someone is next to you; to catch you when you faint.. :P
