Thomas the Tank Engine and Fallout 4 are responsible for 2016's first dumb video.
This latest mod, called Really Useful Fallout, replaces plenty of objects in the game with a Thomas the Tank Engine model. These include Deathclaws, Vertibirds, Liberty Prime, and other miscellanea, such as missiles.
It's created by Trainwiz and he's even edited a goofy trailer for it. You can check installation instructions and download it from here.
