"Give a hoot, don't pollute" was a hard adage to obey when, every time I went camping, there was no place to put my trash, and I had to respond to the slogan with "I'm leavin' it on the ground 'cause there's no trash can around!"
Sorry, Woodsy. By the way, Jeff, the gunman in that Jack Benny sketch was legendary voice actor Mel Blanc. His book, That's Not All, Folks, is the best autobiography I've ever read---dozens of hilarious anecdotes and stories. (Bob Hope's is my second favorite.)
