At the Big Apple Circus, one of the best acts is the trapeze.  The man is usually hanging from the main trapeze and he is holding a woman, while up-side-down, by her arms.  Both of these people are very well trained at what they do, so they are not nervous.  Before the audience got there, they practiced their act multiple times and did not mess up once.  Their main goal while doing this act is to make the audience happy.  Once the audience has entered the tent, they nail their performance.
