Who could forget the zany Captain Kangaroo (Bob Keeshan), Mr. Green Jeans and all those who said "Good Morning, Captain!" (such as William Shatner, Leonard Nimoy and others). Captain Kangaroo was on CBS for nearly 30 years until 1984.
Bob Keeshan had two pioneering roles in children’s television: as the original Clarabell the Clown on the Howdy Doody Show from 1948 to 1952 and, most famously, as Captain Kangaroo from 1955 to 1992. Keeshan died on January 23, 2004 at the age of 76. Captain Kangaroo aired on CBS and then PBS for six decades earning numerous awards, including three Emmys.
