"Oh, uh, nice to meet you." Abruptly aware of his rudeness, Usopp nodded his head directly at Clark. "I'm the great Captain Usopp." Noticing Clark's eyes trying not to focus on his nose, he scratched the side of it as though self-consciously.

It is a pretty great nose.

"The guy's probably trying to keep" dumb "people from running into the Sun Room and getting kicked around like... like that other guy," he added on the side to Luffy. It was logical, and suddenly Usopp realized that if that were right, he owed this guy for standing between his errant Captain and the Room of Doom.
