Scary Jack in the Box

He's not doing anything, but that doesn't stop him from being scary.

A jack-in-the-box is often a staple of childhood playtime and entertainment. Most times, it can be a fun toy for children to play with, but occasionally, it can also be a form of Nightmare Fuel for some. Either way, you can expect to see jack-in-the-boxes pop up in media.

Double subverted with the Farmers' Insurance commercial featuring a giant Jack-In-The-Box that fills the entire front of a classroom.

However, on the "POP" note nothing happens... until about five seconds later when a space capsule falls through the ceiling and crushes the Jack-In-The-Box.
