Well easy does not mean super profitable but the easiest is to get started with joining a couple of faucets and build up from there. check out the micro earnings forum here for a list of the newer ones and discussion:

I also recommend taking a look at the faucet rotator below since it introduces you to a good amount of faucets. It also shares your referral link randomly to new users each time they sign up to a site on the rotator. Again it wont make you rich but its a welcome boost to whatever satoshi you may make on your own.
