He is funny in everything he's in! Richard is not like all other comedians. He can take the semi-funny words of the scripts and make them hilarious! As much as I love Bill Lawrence, "Spin City" had some forced laughs. But not with Richard. When the characters were discussing his ways of saving money, his character responded "Not money. Nine THOUSAND dollars!" The way that he said it, I was rolling on the floor. He is my favorite Scrubs guest star, which is saying a lot because that show has had a lot of good ones.
Richard is charming, and I especially love his speaking voice. I rate him as "underused" because he should be in every scene of every show that he's on!
