They recently had a special on National Geographic about trying to catch a
croc in Africa believed to have eaten over one hundred humans. It was big
croc. You swim with it. I'm scared. It is much faster in water, can hold its
breath much longer, and is much bigger and stronger.

I've been looked over by a lioness that considered me to be food but I think
my chances were better with it. At least me and my buddies could see the
bleeping thing coming, maybe, and enough rocks might discourage it. In the
water there is no chance.
