If you can’t do, teach, if you can’t teach, report the news.

But if you do report the news, never go on jepordy and prove what we already know...you can’t learn!

[Lancey Howard]

If you can’t do, teach, if you can’t teach, report the news.

The way I always heard it was:
"If you can’t do, teach. If you can’t teach, teach gym. If you're not coordinated enough to do a jumping jack, report the news."
