I remember listening to his radio show as a kid. I heard the adults laughing out loud at the things the kids said. It sounded corny then and his shows have dated badly, a product of a time when children could get attention by saying innocently silly things.
When his daughter committed suicide, a national newspaper ran a story headlined 'Kids Do the Darndest Things' and received a lot of criticism . I thought the turn of phrase was quite funny - although in the context of suicide, bordering on poor taste.
