Clock...

I heard an interesting phrase yesterday.
"Even a broken clock is right twice a day"
No origin needed. But under what circumstance would you use this phrase.
Is it wit or profound?
Thanks

It's been around a long time. You use it when a poor thinker--or someone who always harps on the same message--happens to have spoken the truth this time because of sheer luck or because circumstances have changed. Or you use it to dismiss someone you don't like; = "Just because he's right this once doesn't mean he knows how to reason."
Wit vs. profound? Hard to say--and how much of a difference is there anyway? I suppose it was witty the first time it was said.
