Time Travel Fund

This is nearly as clever as the Time Travel Convention last spring. Theoretically interesting and logically convincing, save for one very unlikely assumption, namely the possibility of time travel. The failure of the convention could be argued as proof of the impossibility of backwards time travel, and I don't see how a person could be "retrieved" without such technology, but, damn, I'm almost ready to give the guys a dollar just for the idea. Clever clever.
