Quote by Billy

"I'm a big fan of science!"

"Mandy, wouldn't it be great if we could stay young forever?"

"Why does everything have to be so complicated?"

"That's the most beautiful thing I've ever seen!"

"Never underestimate the power of a good laugh."

"Laughter is the best medicine."

"A good laugh is the best medicine."

"Laughter is contagious and wonderful."
