... A smiling baby.
A friend and I recently spent some time marvelling at the wondrous healing powers of baby smiles. Nothing can brighten your day like a big gummy grin and a gurgling squeak of uncontrolled joy. We decided if you could bottle baby smiles and spread them all over the world there would be a whole lot less hate and a whole lot more peace on earth and goodwill to men (And women. How about people? Stupid gendered language. Baby smiles could get rid of that too I bet). Then we realized bottling baby smiles sounds harmful to babies and just... kinda sick.
So, here's my contribution for the day to world peace.
