Gharial...

I heard that the muscles which close an alligator or crocodile's mouth are tremendously strong, but the muscles to open their jaws, are much weaker. This allows you to hold their mouth shut while wrestling them. It looks like the Gharial would be easy to wrestle because you could hold his jaws closed with one hand and tickle his underside with your other hand, until he surrendered from sheer exhaustion. This, of course, is just an unproven theory, until I get the nerve to jump into the Gharial exhibit...
