There have been many great singing duos through the years. Hall and Oates, Sonny and Cher, Simon and Garfunkel, just to name a few. Then you have the stars of this video. A guy, who I assume is in the shower, and his faithful German Shepherd, who patiently waits for him. Watch and listen as the guy starts out solo, but then the German Shepherd decides he does NOT want to be left out. What results is amazing harmonies. I think.
