The US Open Tennis Twitter account has 2 million followers. That's 2 million people who had their hopes dashed in an instant. Us Open dropped an April Fool's tweet saying they were adding puppies to their ball-retrieval team, and people REALLY want it to happen (although it never will).
Twitter was swift to react to the delightful idea of Corgi's retrieving balls at the US Open. But it was only a fever dream.
