I mean, tis the season.
I miss Halloween shows. Baseball really F'd Treehouse of Horror to death, and the constant dilution of The Simpsons is just sad.
I think my favorite "Halloween Episode" was the slasher episode of Boy Meets World. It mocked slashers, while not being rude with the mockery. They even brought in Jennifer Love Hewitt to guest star.
And it pulled one of the few acceptable "it was all a dream" endings to reset to status quo.
I also deeply loved the first season of Scream Queens. So Stupid, So Mean, So Fun. Of course Ryan Murphy had to Ryan Murphy it up.
