I well remember watching Captain Kangaroo in the late 50s and early 60s. Sorry to say, but Mr. Green Jeans just creeped me out. He was spooky. He hardly every talked, he stood there like a looming giant, and he did alot of staring straight ahead. Thirty years later, this type of character was cast as the killer in every chainsaw massacre movie.
I found Miss Connie on Romper Room to be far more endearing.
