On Wednesdays, the cast and writers sit around a table and begin reading through the sketches. This is the first time that the guest host typically sees the full sketches in their written format. Lorne and his production team sift through the sketches and determine which ones should go through and which ones get tossed. The approved sketches will fall into two piles- ones that are good as-is and ones that need further polishing. (Most sketches fall into the latter pile.) Since most writers will see their scripts cut at this point, they will often partner with another writer to begin the process of polishing an approved sketch.
