Favourite? Time and Punishment
Pure classic.
HM to nightmare cafeteria from the same episode almost entirely for Skinners various lines ("wait, scratch that last one")
Just some good ol' Burns and Smithers fun really.
The best use of Kang and Kodos
Yeah, yeah it's stupid as anything but younger me would be upset if I didn't admit to how much loved this one at the time, heck it's still pretty amusing for its sheer absurdity.
In general this batch of Halloween shorts were pretty solid, I also dug the one beforehand based on fairy tales, the ending bit just makes it ("but the concerts at eight....")
