Kristen absolutely perfectly embodies Dick's character in this episode, from his mannerisms to his cadence, and in doing so shows up John Lithgow's not quite as up to scratch depiction of the goofy but forceful Sally. Every series should have an episode like this so that actresses can use them to show their worth and earn equal (or in this case greater!) pay, which I suspect was not the case as it rarely is. John's performance relies a little too much on playing a simpering woman, which is a shame as this is a series that doesn't generally negatively stereotype women. Kristen more than makes up for John here though.
