Today I picked up two sets of Gamescience dice (for $5/set!) and while inking them came up with the following "tribute" to the Colonel and his dice.
George's Lucky Green Twenty Sider
This object appears to be a small, green plastic polyhedral dice with twenty sides numbered either from one through to twenty or zero through to nine twice. If closely examined one will observe that it is slightly "egg-shaped."If the bearer of this dice ever dies as the direct result of a failed saving throw they are allowed to "turn back the clock" and make a second saving throw with a +5 modifier. Once a character's life has been saved by this dice it disappears forever.
