Kids are great, aren’t they? Well, when they’re not busy making your Saturday mornings a living hell or embarrassing you in public, that is. Of course, even before they are able to speak, they still find ways to keep you on your toes. Just ask this grandfather who decided that bouncing one of his twin granddaughters directly above his face was a good idea. Let’s hope he’s got fast reflexes, because he’s going to need them.

Our thanks to Joshua Debolt for bringing this lovely video of his daughter to our attention.
