If I was rich and famous, there's only one thing I'd want to do — give back to those who need it!
Well, okay, I also might like to purchase a big vacation house somewhere in the Bahamas to escape to every time the temperature drops below "light jacket" levels, and maybe I'd finally be able to afford adopting all the pets I'd ever want (does Jason Momoa count as a pet? Asking for a friend), but the most important thing that I would do with my money is give back to those who need it.
