Patiently signing autographs for a bunch of ugly children?
Becoming the honorary chief of a Native American tribe?
Grabbing a stampeding horse by the reigns and leading it away from a potential victim?
Riding a horse?
Riding a dolphin?
Driving a stage coach?
Fighting an octopus...underwater?
Kicking a jungle cat out of a tree...while swinging from a vine...by his mouth?
And he did all of that without the benefit of having hands. Can you imagine if Rex had opposable thumbs? He'd be unstoppable!
