I saw this picture on an advertising display at a grocery store.  Let's evaluate:

-Scary jack-o-lantern: check
-Burning Halloween text: check
-Bat and witch silhouettes upon full moon: check
-Ghost of Abraham Lincoln: . . . huh?

Since when was Pres #16 the subject of anyone's fright night?  I still chuckle when I see this and I still have no idea why he's in this picture, lol.  Anyone have a good explanation for us?  I sure don't.
