On Monday mornings the actors read the script. The writers listen to hear how it sounds and then rewrite. On Tuesday the cast acts out the revised script, and it is again rewritten on Tuesday night - usually until really late at night. On Wednesday the process repeats itself, and then the rewrite is finished. Thursday the writers aren't at the stage, and on Friday they come for the taping, where they may have to change lines if the audience doesn't respond to something.
