"When I was first approached to play the Riddler, I thought it was a joke. Then I discovered the show had a good script and agreed to do the role. Now I am in love with the character. I developed the Riddler's fiendish laugh at Hollywood parties. I listened to myself laugh and discovered that the funniest jokes brought out the high-pitched giggle I use on the show. With further study, I came to realize that it wasn't so much how I laughed as what I laughed at that created the sense of menace."
