Simpsons fans know that Sideshow Bob has been out for deadly revenge ever since Bart snitched and sent him to prison (for the first of six times) all the way back in Season One's "Krusty Gets Busted."

Twenty five years later, the murderous moment has finally arrived in the upcoming Simpsons Halloween special Treehouse of Horror XXVI, which airs Oct. 25 on FOX. Bob (Kelsey Grammer) seems to really be savoring the moment, over and over and over.

Although this is Treehouse of Horror we're talking about here, so if we're being real, pretty much everyone has died in one of these and it doesn't really count. But, still! Sweet revenge, finally.
