It's always fun to see an actor of one of your favorite shows do something different.  Here, it's Zachary Levi from NBC's spy dramedy Chuck singing a duet with former American Idol runner-up Katharine McPhee.   

Chuck is finishing its third season, but I only started watching it in January on Blu-Rays.  The show is the perfect blend of action, comedy, and romance.  50 episodes later, I'm finally caught up with only four shows remaining this season.  Chuck is borderline for renewal, but I'm hopeful for a 4th season.
