Dr. Seuss in Justice Kagan's Yates dissent

I rarely laugh out loud when reading Supreme Court decisions. One exception occurred a few minutes ago as I read Justice Kagan's dissent in Yates v. United States. As authority for the proposition that a fish is a discrete thing that possesses physical form, Justice Kagan throws a "see generally" to Dr. Seuss, One Fish Two Fish Red Fish Blue Fish (1960). Demonstrating some restraint later in the dissent, Justice Kagan did not provide the obvious Dr. Seuss citation ( "cf. Horton Hatches the Egg") for the assertion that "Congress said what it meant and meant what it said."
