The Procession of the Animals (1866)
Several hundred people showed up at the gates of the London Zoological Society demanding entrance in order to see the "procession of the animals." However, the Society was closed that day, it being Easter Sunday, and the guard refused to admit them. The members of the crowd insistently showed the guard their tickets and again demanded entrance. The tickets, which had cost them one penny each (considerably cheaper than the usual sixpence admission), read:
Subscribers Tickets—Admit bearer to the Zoological gardens on Easter Sunday. The procession of the animals will take place at 3 o'clock, and this ticket will not be available after that hour.—J.C. Wildboar, Secretary.
The guard explained that the tickets were not valid, and that they were all victims of an april fool's day prank. Upon hearing this, the crowd grew restless, insisting loudly that they had paid their admission and were determined to see the animals of the zoo all walk in procession. Before the situation became out of hand, an extra force of constables arrived and dispersed the crowd.
The Zoological Society investigated the situation and discovered that the tickets had been sold by Mrs. Sarah Marks, a bookseller. The Society pressed charges against her, but withdrew them when she wrote a letter apologizing for her behavior.
