Something that is impossible without taking off EVERY last zig. In order to take off a zig you must know what you doing. This is the reason WHY you must take off the zig.
Basically, it's like playing a horrible video game. "Damn, that storyline is great... but the game is
boring... must
play..."
McDoodleBob: So, why should I
take of every zig? Just because I
KNOW what I do?
Captain: No, take off every zig... for great justice...
