The Chicken Roaster

George reveals a strategy to guarantee a second date with women - leaving an object behind at their place.  However, this strategy gets Elaine into trouble, when George leaves behind a sable hat she shouldn't have charged to the Peterman expense account.  Meanwhile, the red neon sign of a new Kenny Rogers Roasters restaurant beams directly into Kramer's apartment.  Jerry and Kramer then switch apartments, and end up switching personalities as well.
