One of my all-time favorites is Jazz/Blues performer and composer Mose Allison. Some of the most pungent and clever lyrics I've heard are his. Once example:

YOUR MIND IS ON VACATION

You sittin' here and yakkin' right in my face,
I guess I'm gonna have to put you in your place.
You know if silence was golden,
You couldn't raise a dime,
Because your mind is on vacation and your mouth is workin' overtime.

You quotin' figures and droppin' names,
You tellin' stories about the dames
You're over-laughin' when things ain't funny
You tryin' to sound like you're big money,
You know if talk was criminal,
You'd lead a life of crime,
Because your mind is on vacation and your mouth is workin' overtime.


You know that life is short,
Talk is cheap;
Don't be makin' promises that you can't keep.
You don't like this little song I'm singin'
Just grin and bear it,
All I can say is if the shoe fits wear it,
If you must keep talkin'
Please try to make it rhyme,
Because your mind is on vacation and your mouth is workin' overtime.
