If you could tame any animal in the world so you could ride it, what would it be and why?

I believe I added this question as a joke in week six of blogs assuming I would never have to answer it; however, I have decided that I want to answer it now because it is a pretty good question. If I could tame any animal, it would totally be a lion. Picturing myself riding a lion seems like a scene straight out of the movie, Narnia (which is a great movie by the way). I would imagine riding the king of the animal kingdom sort of makes you the god of the animal kingdom. Also, I can only imagine the power one would feel holding the reigns to a lion. I could get used to riding a lion, killing a zebra here and there. If they were to come out with lion races (as opposed to horse races), you could count on me being in attendence to one of those. Anyways, riding a lion would be an amazing experience and I hope, one day, we will be able to do it.
