Amos was all but dying from laughter until that crazy old man cropped up. He almost immediately stopped laughing and blinked back at Charity, looking just as confused if not more.
He shook his head and gave the old man a very strange look, "Excuse me sir, but that's hardly uh..."

Amos frowned slightly, there was something very familiar about that crazy old geezer.
