When I was a kid I lived near Marineland. It was a common family outing. I remember playing catch with dolphins. Some lived in a tank surrounded by an outer wall. The dolphins had a basketball and would fling it our way. We'd catch it and toss it back.
Half the time the dolphin's toss landed between his tank and the safety wall. We'd have to fish it out with a stick, coaxing it up the wall untill we could grab it. The dolphin watched, tipping his head and body so he could view our struggle. I think he liked that. He was strong enough to toss the ball beyond the wall. He wanted to see us sweat.
"Isn't he cruel," his tankmates probably observed, "The way he keeps teasing those dumb animals!"
