Episode question

[ethanmuse]

There was a radio episode where Jack was criticizing someone and Mary says, "Oh, you're just jealous because he's handsome and you're you." Jack responds by saying, "Mary, if you think I'm homely, just say so." And Rochester says, "It was perfectly clear to me." I know I've heard the episode, but could somebody please refresh my memory as to which episode it is?
