"When you look at the balls, careful you must be. For the balls look back."
"Balls you must have my young Padawan."
"Powerful you have become, the balls I sense in you."
"Feel the balls!"
"Great warrior. Balls do not make one great!"
"Balls matters not. Look at me. Judge me by my balls, do you? Hmm? Hmm. And well you should not."
All from the wisdom of Master Yoda.
