Why do we adopt pets? Most of us have lots of reasons, but a big one shared by everyone is this: They bring us joy.

The kind of joy a Greyhound named Mosley felt when his loving human got him his very first pair of genuine Batman pajamas just in time for that first snowfall at the dog park.

Sadly, people can’t run as fast as Greyhounds can. Happily, however,  we can watch YouTube, where this moment of pure happiness has racked up nearly 1 million views and counting.

We love you, Mosley! You’re zooming for all of us!

Watch him below, and spread the joy.

Happy #FeelGoodFriday!
