Has anyone on Fluther ever attended a "Become financially dependent & make a ton of money with my sure & proven plan",work shop ?

I have always wondered whether they are legit or just scams.
I’m talking about those late night infomercials telling the story of how some guy was living paycheck to paycheck and stumbled across and/or designed a quick and easy method/plan to make money hands over fist with minimal investment and is willing to teach me how to do so,in one of his free work shops coming to my area ???!!
*That makes as much sense as me going on TV,claiming while hiking through the mountains,I stumbled upon a site containing gold nuggets and now I will show you where it is and how to dig them out so you can become rich just like me,why in the world wouldn’t I just keep my mouth shut ,“NOT” share the wealth and become even richer !
