Hah!! These are hysterical. I love it! Very creative, well-done, and funny as heck.
Not something that everyone will love (obviously!) but as someone who has plenty of experience with death of loved ones, I firmly believe that the best way to handle sorrow and pain is with laughter and art. When I hurt the worst, that's when I laugh the loudest, and these Sunbonnet Sue murders tickle that part of me, in a harmless and friendly sort of way.
Of course, I'm a big Neil Gaiman and Terry Pratchett fan too, so maybe we're just similarly warped? LOL
