There's a scene from the first Jurassic Park movie where the kids are hiding from the dinosaurs in a huge commercial kitchen. The "experts" monitoring in another room convince the kids' grandfather that they are safe--unless the dinosaurs have suddenly learned how to turn doorknobs.
The scene cuts back to the kitchen door--specifically the knob that is now slowly turning. Enter the doorknob-turning Velociraptor.

Yup. He has learned how to open doors. Lock up your daughters and hide your Quaker instant oatmeal.
