Pennies for Cancer
This punch-card charity game from the late 1940's was a fund raising device for the Damon Runyon Cancer Research Foundation. One cent would allow the donor to play a few innings of a baseball "game" on the honor system. The foundation still exists, it claims to give 100% of donations to cancer research.
Dichloroacetic acid is a chemical compound that has shown some effectiveness in treating mice; human studies have been very limited and inconclusive. It is being used as a non-approved drug by doctors and has been used by individuals experimenting on themselves. It costs pennies per dose.
There are no large scale tests currently underway- its manufacture is cheap and it is out of patent so there is no financial impetus for development.
A quick search of the Damon Runyon site brought no results for Dichloroacetic acid.
