Because if you wish hard enough the internet will provide, this is a video of a group of kittens playing peek-a-boo with a man's finger from their hideout in a bush. Admittedly, that looks like a pretty solid game of peek-a-boo. I remember when I was a kid and my dad and I would play peek-a-boo he'd put a scary clown mask on and that's why I have trust issues now and don't talk to my family anymore except my little sister, and I really only talk to her when she changes her HBO GO password.
Keep going for the video.
Thanks to Stephanie B, who agrees we could all use a little more kitten peek-a-boo in our lives.
