The Supreme Court decides "What is Golf" (on a T-Shirt)

I just found a very cute CafePress store which has legal quotes and other stuff on T-Shirts -- for example, Justice Scalia's dissent in PGA Tour v. Martin:

It has been rendered the solemn duty of the Supreme Court of the United States . . . to decide What is Golf.

Other good quotes include Learned Hand's opinions on the Income Tax laws, useful Latin legalese terms, and Justice Thomas's supreme understatement in Kelo v. New London:

Something has gone seriously awry with this Court's interpretation of the Constitution.
