* OutlivedItsCreator: Following Bil Keane's death in November 2011, son Jeff (on whom Jeffy is based) has continued to go solo. He had previously helped Dad on the strip starting in the 2000s.
* RecycledScript: Having been around as long as it has, an increasing number of panels have been "remade" over the years, most noticably Christmas-related ones; there are also long stretches of reruns from ''decades ago''. Since the strip's humor hasn't evolved, it's hard to tell which are remade/reruns and which aren't if one didn't read the panels back when they were new or in the book collections.
