Fund Your Future Time Travel
Tired of investing in boring old stocks and bonds? Why not put some cash into your future? For a mere $10, you can join a unique investment group, the Time Travel Fund. The concept is simple. You deposit those greenbacks with the fund managers and they buy extremely long-term investments that will earn a ridiculous amount of compound interest. All you have to do is keep your address current on the membership database. Once all time-travel's scientific and social details are worked out in the future, the Time Travel Fund will use your accumulated wealth to pay for someone to go back in time and collect you just before your imminent death. The find will even provide you with any required housing and education in the future so that you're not too time-lagged. The organizers point out that they can't guarantee that the plan will work but, hey - it's a chance and it's fun. It would certainly diversify your investment portfolio.
