Lindsey Stirling
American Musician
There are so many things that can go wrong while performing. I've had violin strings break; I've had pants that were slowly falling down, and I'd have to pull them up in between every song; my hairpiece was falling out, so a big chunk of hair was just flapping around as I danced, and I've completely fallen on my butt.
Quote examples
John Schneider
American Actor
Some people treat seeing me as if they just won a car on 'The Price is Right.' The feet get going, and the hands start flapping, and it's really quite amazing. It's a little scary: you can't have more than two or three of them at the same time because someone might get hurt. But it's great fun.
Quote examples
Mel Brooks
American Comedian

Quote examples
Joyce Meyer
American Author
There are a lot of 'chicken Christians.' Chickens are generally afraid of life, and they seldom fly or reach their potential in life. And when a storm comes, all they seem to do is flap around the chicken yard, stirring up dirt and running to the chicken house.

Some people say that in stressful situations I can seem unflappable, and I think that's partly because I'm always kind of internally flapped.
