Porter Ballard is already so good at jump rope that he has to add backflips into his routine to give himself a challenge. He's able to land perfect backflips and never once hit the jump rope spinning around his body. We could totally do that too, but we just don't feel like it.
Next, surf simulators at a water park are a lot of fun, unless you find yourself falling off the body board over and over again. It's okay though, as long as nobody is there to record you falling over in the water multiple times and put the video online.
