By the way, there was an urban myth going around for years about Bob Keeshan.

Supposedly, Lee Marvin claimed they saw combat together at Iwo Jima and that the man to later become Captain Kangaroo was the bravest man he ever knew.

It's not true.

Neither is the one about Mr. Greenjeans being Frank Zappa's or Ted Nugent's dad. (I heard he was Alice Cooper's father when I was a teen).

But apparently it is true that Mr. Keeshan's kids didn't know their dad was the Captain when they were young.
