Double My Money

I received a phone call one day from someone that knows I work in the financial world. "Joe" is a young, sweet boy that I'm sure just wanted to help a friend. Joe gives me the phone number of a friend of his, and tells me that this friend "Brian" has some money that he wants to invest and needs my help. So I call Brian. Here's the Cliff's Notes version of the conversation:

Sam: Hi Brian, this is Sam from XX company. How are you today? Joe told me that you needed some financial advice.

Brian: Yeah, I have some money that I'd like to invest.

Sam: Well, Brian I can't give you advice over the phone, but I'd be willing to meet with you and discuss your options. How much money are you looking to invest and what do you want to accomplish with this money?

Brian: I have 1000 dollars and I want to double my money within six months. But I don't want to take on a lot of risk.

I'm driving while I'm having this conversation, and at this point I'm trying not to crash my car because I'm laughing so hard. My first thought was "Red or Black?". I almost gave Brian the directions to the nearest casino. Or maybe Vegas. It's only five hours away.
