Don Knotts, who won five Emmys for his portrayal of fumbling deputy Barney Fife on The Andy Griffith Show — and also is well remembered for playing Three's Company's hideously clad "lady killer" landlord, Mr. Furley — died Friday of pulmonary and respiratory complications. He was 81. "Don was a small man... but everything else about him was large: his mind, his expressions," Andy Griffith tells the Associated Press. "Don was special. There's nobody like him." Knotts' half-century career also included the late-'50s variety show The Steve Allen Show (on which he was an original cast member) and such films as The Incredible Mr. Limpet and 1998's Pleasantville.
