Wow, David Letterman must really like Joe Wong. Wong made his fourth appearance on The Late Show last Friday night. I saw Joe perform last Fall when he was in San Francisco and he remembered me when we first met a few years ago (also in San Francisco). We chatted briefly and was impressed to learn that Joe quit his day job, and has been doing comedy full-time now. I think Joe’ best (and longest set) that’s available online was when he hosted the Annual Radio & TV Correspondents’ Dinner with Vice President Joe Biden as the guest of honor.
