And since we are now on the subject of unusual encounters with whopper fish, somewhere amongst my disorganized collection of vacation videos I have some footage of a whale shark being ridden by the first mate of our Hawaiian fishing charter.  

We happened upon the beast while returning from our charter.  We stopped for some video and the first mate said he'd be willing to give us some video we'd never forget.  I begged the captain to let me jump in for a ride, too, but he was having none of that.  I still regret not just doing it anyway.  We were already on the way back.  What was he going to do?  Take me home immediately?  That was already in progress!
