Very funny episode with Jack trying to prove he's a good friend to Will - while Pat Lupone sits nearby. Jack wants her hair and the final scene where Pat is singing with Will - and Jack's face when he takes out the scissor to cut her hair - pure comedy classic!!!
Also funny is Scott using Grace to sack Karen - and then it turns on him - as Grace/Karen catch him out. The scene where Karen turns around in the chair with a cat - and Scott drinking something "odd" - another comedy classic!!!
