For some things, you can't even sensibly measure the mean. For example, if you're measuring the mean response time for a service, a single failure/timeout makes the mean response time infinite (because 100 years from now the response still hasn't been received).

It's indeed always worth pointing that a mean may or may not exist. Same with variances/standard-deviation.

The central limit theorem seems to have given people the slightly wrong idea that things will always average out eventually.
