Sometimes, you just can't stop yourself. You know better, but you have to do it anyway. You think, "Hey! I know how this ends!", but you still do it anyway.
Sure, leaping out of the water, snatching a fish in your teeth out of thin air, and diving through a hoop gets a reaction at the local pool. When you do it the second time, the shock value is greatly reduced. It's just not as good once it's reporpoised.
