Just do the lame adsense thing, find a popular subject that no one has written about, or just make a random blogg site. and put google adsense on there and go to websites and forums and advertise your site and hope people click on the adsense and if u get a lot of website hits sell advertising space
I think the best online job that you can do is something with taking phone calls over the phone for some agency. You really have to be careful with the things you do online especially job related.
You can earn money online by selling domains.If you are interested get the reseller package at Goresellers.com .Once you become a reseller , you will get the domains at low price & you can sell it to others.
