From the Wikipedia entry on GI Joe comes the news that the flexible plastic used for the action figures' hands in the '70's -- the source of GI Joe's infamous "Kung-Fu Grip" -- has degraded with age, leaving even figures in unopened boxes missing hands.
Perhaps it was inevitable. Yet it's still poignant to think that as Joe has aged, even his mighty Kung-Fu Grip has failed him.
Old soldiers never die. They just lose their grip.
