A dancing fish

Really, an old clip of Abe Vigoda, who played the character Phil Fish in the show Barney Miller and famously Sal Tessio in The Godfather, gives a glimpse of his singing and dancing abilities: 

A good sport, he joked that when people met him on the street in his later years, they usually expressed shock that he was still alive.  It didn't seem to phase him.  People with that level of humor and understanding always impresses me.
