'Common sense is the guy that tells you that you ought to have your brakes relined last week before you smashed a front end. Common sense is the Monday morning quarterback who could have won the ball game if he had been on the team. But he never is. He's high up in the stands with a flask on his hip. Common sense is the little man in the grey suit who never makes a mistake in addition. But it's always someone else's money he's adding up.

Summary

This quote satirically portrays common sense as an elusive and hypocritical character. It suggests that common sense is often seen as a hindsight voice, advising on what should have been done in the past. However, it never seems to be present when needed. Common sense is depicted as a spectator, absent from the field of action, enjoying comfort and observing others' mistakes. It further alludes to common sense as a meticulous individual unerringly keeping track of others' financial matters but never facing consequences for their own actions. Ultimately, the quote questions the true reliability and practicality of common sense.
