I did this the other weekend.except replace "monsters" with "zombies." Someone was shooting off and I thought, "What if those are rifles? What if it's zombies?" This is why I choose not to watch scary movies! :) I've got "scary" covered.
Yes, penguins do have knees! A penguin’s leg is composed of a short femur, knee, tibia and fibula. The upper leg bones are not visible as they are covered in feathers, giving the penguin the illusion of short legs and no knees. No go the fuck to sleep.
