Joe could rhapsodize about some old beer aficionado who gave him the original funding for his first bar. He really was nice, although also a bit of a hermit, he'd never met with Joe in person but man did that guy know his beers. And Duncan sees Methos out of the corner of his eye and the old guy is hiding a smile. It take a moment but when the clue finally clicks, Duncan snorts beer out his nose. And Joe wonders what's going on.
