I like Garrison Keilor. He is right up there with Mark Twain, Will Rodgers and other humorists.
One problem. He is a natural snob. He looks down his nose at too many "other" entertainers.
Can't people ever be talented and bright without cutting on others?
You distance to get enough objectivity to be humorous.
But should that distance be horizontal or as is the case with GK -vertical. He's too God-Like.
