Two Choices

Think about how depressing it would be each day to see and hear birds flying above you, knowing that you can never be up there? For a bird, flightlessness is depression. And if you've ever seen an ostrich, you can tell it's depressed. All they do is run around and stick their heads in the ground when scared. we all know that a flying ostrich would be a happy one.

Another choice, and my preferred choice, is to give the wings to the largest lizard on the planet, the Komodo Dragon. Because then there would actually exist a dragon in the world! I would ride him and train him how to protect viking villages. I would ride around to epic music and I might even get a cute blonde girlfriend. It would be the best this ever. 

So there you have it, to an ostrich or a lizard.
