Feds 'n' Heads is a fairly basic roll and move game based on the designer's own famous comic strip, The Fabulous Furry Freak Brothers. The game bears more than a passing resemblance to Monopoly (collect money for passing go, roll a double to get out of jail or pay $50 etc) but the board is more sprawling and includes several junctions and special squares.
The basic objective is to score (collect) one Key (a kilogram, or 35 ounces) of grass and return home with it.
From the cover:
"Feds 'n' Heads, the game of pot luck - wherein one tries to keep on the grass while avoiding the attendant pitfalls of rip-offs, bummers, burns and busts."
