I like the idea that the guy who 'perfected' the Frisbee had. His ashes are to be molded into Frisbees so he can fly above the earth even in death. May not be "forever," but what a neat idea while the Frisbees last!

Besides, I guess you could re-mold the torn up, chewed up Frisbees quite a few times before all traces of the guy's ashes disappeared.
