What did mrgreen jeans do on captain kangaroo?

He was a farmer who always wore Green Jeans, hence the name. with these two the show almost approximated a Juvenile (Johnny Carson) as they had occasional guest characters-live. Captain K read books on the air- and sort of para-cartoon things like the Paddle To the Sea, and various sub themes- for example the somewhat communistic short story- Caps for Sale- was themed with a lesson on various types of occupational headgear.
