In a similar vein
Okay, curiosity: the phrase "in a similar vein" Origins? Have seen it 'vain,' 'vane,' and 'vein'
It's vein all right. Thoughts and conversations flow as blood flows, along a path. Does "Mad" magazine still exist? Their motto was "Humor in a Jugular Vein."
It does. SS
There's even a Mad TV show now. Check your local Fox affiliate's listings for late Saturday night.
