The 'Canna Chopper' is an unmanned miniature helicopter fitted with "odor and video detection instruments" that locates your field of (pipe) dreams in the Netherlands and notifies authorities. Needless to say, it's the polar opposite of a ROFLCOPTER.
On its maiden voyage it managed to locate a cannabis farm and officers arrested seven growers and recovered several kilos of the outlawed weed. Now all it needs is a gun attached to its underside and it could make its own arrests.
Robot, kill it. And also, stay the hell away from my basement, nothing to see down there. Smell -- what smell? Well, can't say I didn't warn you. *pew pew*
Thanks to twellve and Mr. Fancy, who are both smart enough to know that drugs your screw up brain real bad.
