Simpsons Halloween

Here, Dr. Hibber is trying to reassure Hugo (Bart’s twin who’s been locked in the attic for years) that everything is OK. He picks up a mirror and says "I bet you’ve never even seen your own reflection have you?" As Hugo moves closer to see his reflection, Hibbert reveals that the mirror is only an empty frame and slugs Hugo in the face.

I love this scene so much, it’s scary. Cracks me up every single time. :D
