Voice Recording - Best Practices for Post

I have a question for anyone who does voice recording of an actor or voice talent.

Assume once you're done recording (or shooting) that getting that actor back for a pickup line is cost prohibitive. Does anyone have a generic sentence or phrase they ask the actor to record to capture all the basic speech structures so you have what you need in your editing toolbox if/when you run into a missed word or a word that gets stepped on by a background sound?

Thanks for any help or thoughts.
