From a New York Times report of protests in Moscow (emphasis mine):
An encampment in a Moscow park ... is modeled on Occupy Wall Street. ... On Thursday, the police detained eight young women in pig costumes. A cow appeared over the weekend, evidently to protest Russia's accession to the World Trade Organization.
Olga Romanova, a longtime opposition activist, said she had given up trying to explain the situation in letters to her husband, who is in prison.
"I started to write, 'There's a wedding taking place here right now, and now a cow has come,' " Ms. Romanova said. "Then I understood that I have to cross it all out because he'll think that I've gone crazy with grief or something is happening with me. How will they explain to Putin? There was a wedding. A cow came. How will they explain that?"
