A Bit of Humor

This joke was sent to me in an email yesterday and I thought it was so cute. I'm going to post it here to add a bit of humor.....
You are on a horse, galloping at a constant speed. On your right side is a sharp drop off, and on your left side is an elephant traveling at the same speed as you. Directly in front of you is a galloping kangaroo and your horse is unable to overtake it.
Behind you is a lion running at the same speed as you and the Kangaroo.What must you do to safely get out of this highly dangerous situation?
