... in Supreme Court oral arguments.
Is a sense of humor a mark of a good judicial mind? It's Scalia and then Breyer with the most laughs, and Roberts is off to a good start.
To get laughs from your sense of humor, of course, you've got to make your observations out loud. Who knows what amusing things Clarence Thomas is thinking in his silence? I know I'd have different thoughts depending on whether I actively engaged in debate with the lawyers. If I did, I'd have to concentrate on the terms of the legal argument. If I didn't, I'd think much more about how the lawyers and judges looked and acted as characters in a human drama -- a very rich source of witty remarks, but nothing you can interpose at oral argument.
ADDED: Why isn't Green Bag available on line? It would be nice to be able to read an link to Professor Wexler's article (the basis for the article I linked to above).
MORE: Gordon Smith aptly observes that counting the laughs mostly only counts which judges think they are funny, since the captive audience will tend to oblige the judge with a laugh when he tries to be funny. What are you going to do? Groan and roll your eyes? Also, the courtroom is a tense and sober place that laughing is a special relief. You might have had any number of things you wanted to laugh at and had to stifle yourself.
