Have you ever heard of face swapping? The concept is simple and hilarious; take a picture of two people (or dogs or anything, really) and swap the heads via Photoshop. Seriously, that's it! The result is a strangely entertaining mix of super creepy and straight up funny stuff that may or may not give you nightmares.

The best part about face swapping is that it can be done in tons of ways. You can switch dad and baby heads or a dog and owner faces if that's what cracks you up. (Or characters from 'Game of Thrones' if that's your thing.) Basically, creativity and creepiness is key here. Check out some of our favorites below.
