To be honest, I'd probably not think anything and just run from the lion. I would be running so fast just hoping the lion didn't catch me and eat me. If running wasn't an option, I would catch the zebra and harness it then ride off into the sunset. If I couldn't ride a zebra, I would probably have to man up and wrestle it like Steve Irwin. The only other thing I could imagine myself doing is just sitting there hoping that the lion doesn't eat me and only eats the zebra. I figure this would also be taking place in Africa and I guess that'd be cool because I've never been there but then the whole being attacked by a lion thing might ruin the entire thing. Before I go there I'll have to read a "How to survive in Africa" book.
