'Tis (?'twas) the season to be frivolous
I missed this at the time, but someone has actually studied humour in the US Supreme Court (for Green Bag, admittedly, but still...). Apparently Scalia J is 19 times as funny as Ginsburg J, measured in number of laughs in the term...
update: Starkoff points out to me that the Green Bag article is available online here.
