916: Unpickable

Explanation

The comic plays on the idea that geeks and nerds will try to break into high-security areas in order to challenge themselves, instead of to steal things. The vault is labelled "unpickable" as a kind of challenge to break into it, while all the valuables are simply stored in a shoe box. Since the vault is unopenable, nerds and geeks would spend all their time on the vault and ignore the seemingly useless shoe box.

The title text continues the theme, with an unsolved 5x5 Rubik cube to further challenge the thief.
