Friday legal puzzler

The State Court of Appeals of Michigan recently had to take up the following issue: If a man is convicted of having sex with a sheep, must he register as a sex offender?

The UCLA professor Eugene Volokh outlines the relevant statutes and links to the court's decision (which reads a bit like William Gaddis's "A Frolic of His Own": deadpan legalese in the face of absurdity that must never be acknowledged).
