Courageous Duckling
This picture of an impossibly cute and courageous duckling was first posted on twitter, on January 4th 2019, along with an invitation to museums to share their own best ducks.
What followed was an unprecedented spontaneous outpouring of ducks. The internet has celebrated International Unsolicited Duck Pic Day on January 4th ever since!
But this is still the best duck to have on a mug.
