Got a case of the Mondays? You won’t be able to hold on to that feeling for long if you watch this video of a two-legged boxer, Duncan Lou Who, as he runs in joy on his first trip the beach.

Watch Duncan Lou Who as he shows the true spirit of animal happiness — even with his missing limbs, he is the picture of pure strength and energy as he runs up and down the shore with his companions.

Duncan Lou Who is living proof that animals, even when “impaired,” are the most beautiful creatures just bursting with lessons for us humans: enjoy life and all that it gives you, Green Monsters, even on the Monday-est of Mondays!
