They want you to throw your common sense out the window.

Intelligence is natural; common sense is a virtue.

The biggest obstacle in the way of human development is lack of common sense.

Because you can't argue with all the fools in the world. It's easier to let them have their way, then trick them when they're not paying attention.

It's just common sense. You don't have to blast music to enjoy it.

Common sense is not so common.
