Prot: Why is a soap bubble round ?
Dr. Mark Powell: "Why is a soap bubble round ?"
Prot: You know, for an educated person, Mark, you repeat things quite a bit. Are you aware of that ? A soap bubble is round because it is the most energy-efficient configuration. Similarly, on your planet I look like you. On K-PAX I look like a K-PAXian.
