Note: Lots of appropriate cursing, baby with a knife.

This is a video of a mother giving her baby a fake plastic knife to go terrorize other family members in its wheeled baby walker. They all respond about how you’d expect — with an expletive and immediately disarming the tyke. Except grandpa, who doesn’t even get up from his computer to take the knife away. Lessons will be learned.
