Rack your brains: A puzzle for all who can count numbers

Of 2006 coins, two are counterfeit, one lighter and one heavier than a true coin. With four weighings on a simple two-pan balance, determine if the two false coins weigh less, the same, or more than two true coins.


A solution (even an internet link to a solution) will be highly appreciated.
