"That will only happen if I have a bout of amnesia or if I feel like mooning someone in the audience"

This quote by Daryl Hannah is an amusing way of expressing her reluctance to carry out in public. She is indicating that the only method she would ever consider performing in front of an audience is if she were to suffer from a bout of amnesia and forget her worry of performing, or if she were to do something outrageous like mooning somebody in the audience. This quote is a funny method of expressing her sensations about carrying out in public, and it also reveals her desire to take dangers and push her boundaries. It is a tip that even if we hesitate of something, we can still discover ways to challenge ourselves and take dangers.
