Brother plays the ultimate prank on his sister using just one light switch

Let's face it, siblings are the worst.

Unless, of course, you're that sibling.

Redditor PNWndn decided to play a prank on his sister with a flick of a light switch. Needless to say his sister and her friends won't be playing with a Ouija board anymore.

As soon as he turned the light switch off, all you can hear is a group of screams from a distant room.

Surprisingly, many users praised him for his work and gave more suggestions on how to torment his sister further. The internet simply has no chill when it comes to sibling pranks.

The thread may have received tons of upvotes, but it might not be worth it if his sister plans a good revenge.
