$10000 is 0.001% of the billionaire's wealth, it doesn't negatively impact the billionaire financially. The question is, how do you convince him to gift you $10000 right there and then?

You should have the freedom to spend the $10,000 as you wish, so solutions involving repayment at a later date, or plans to donate the money on his behalf, do not qualify as valid solutions.

Ideas are rated on a few dimension:
1. Likelihood for it to work (most important)
2. Practicality/Ease of carrying out:
-If the idea involves showing the billionaire an impressive cv, that might not be feasible for everyone

-If the idea involves performing an impressive magic trick on spot, that might not be feasible for everyone
