If you start a diologue line with "As you know-" you might as well stamp INFODUMP on the page.
"As you know..." is not only a notorious lead in for infodumps, it's also bad dialogue. When was the last time you heard it outside of a business meeting? Or heard good dialogue inside of one?
If you see "As you know..." in your script jazz it up (have someone react to how patronizing it is) or cut it out. It rarely leads anywhere worth going.
As you know.
