Get rich quick?

I see all these get rick quick things on tv. I often wonder if theres any truth to any of them. Anyone ever try one? Are there any good ones out there to try? Im not looking to become a millionaire overnight lol i just really need some money..im at the end of my rope here. I have 100 dollars on a credit card and thats about it. :( I lost my job and its been very hard finding a new one. Ive been on about 10 interviews in the past 3 weeks. I didnt get one call back. I dont mean to sound so pitiful, just looking for some help. Thanks.
