Robodex
The Ferris-wheel-type paper-holding device where cyborg-Officer Alex Murphy keeps his colleagues' business cards.
Officer Murphy is all for networking as much as anyone, but he regularly has to "weed" his Robodex of cards that he no longer wants in there, since many of his accumulated contacts turn out to be scum-bangs... lots of Dick Joneses out there who purport to be honorable caring dedicated members of the public or local government, but are actually just trying to line their own pockets, puff their cronies' political standing, alter election-votes, etc.
Get the Robodex mug.
