MAKE MONEY ON GOOGLE!

A friend of mind just emailed me and told me that they left their day job to make money for google (for a small fee) - I thought - mmmmmmmmmmmm - lets research this - What I found is that people can make money by clicking on ADs google on different sites but now their are a bunch of people out their that will help you do this and - well - that costs too - DON'T LEAVE YOUR DAY JOB! - Anyone got a heads up on this?
