hahahahaha
This definitely would work and he would not die, mostly. Tony had fallen from much greater heights and look at him, he was still gorgeous. He gave a final tug of the rope, just in case, because he didn't want to end this adventure with scraped knees and nothing to show for it, then jogged with it in hand back away from the cliff. It wasn't even as though he was the first person to ever do this, although maybe those stories were all about that sturdy pine a few feet down the hill, leaning over the waterfall.
It wasn't like he was getting that rope down now. Very faintly, over the roar of the water, he could hear the voices of the fellow campers in the comparably serene lake below, splashing away innocently in this pre-miracle time. All of that was about to change. With a running start, Tony leapt up, letting the rope carry him well over the edge of the waterfall, then released at the top of his swing.
With a thrilled shout, Tony flailed in the air, found he had plenty of time to right himself and avoid a painful flop, only to make devastating eye contact once facing the lake. His grin turned to a horrified gape and he threw his hands in front of him as though he could slow his fall and avoid the head on collision.
