An exception to every rule?

Going to bed when your mum is tired is one rule I know there is no exception to. Mum is always right, there's another one.

The statement "an exception to every rule" has to be incorrect, whether or not there are any rules with exceptions. If there are rules without exceptions then that means the statement is incorrect by saying that there is an exception. If there are some rules without exceptions then that means the statement is also wrong because that means there is an exception to that rule too. So there must be an exception to that particular rule but then if there are rules with no exceptions then that is wrong.

I recon there must be loads that don't actually have exceptions, including the ones Nannacrocs talking about. Hmmm, how about 'people are born, they live, then they die', I don't think there's any exceptions to that one. Oh and the rule that tea makes everything better, there's no exceptions to that one either.
