If that is a Prince Albert, what is a William the Conqueror?

I am preparing a Victorian Period scavenger hunt for my senior English class. They will search for several of the main characters behind the period – Victoria herself, John Stuart Mill, and Charles Darwin. I am also having them search for myths and interesting facts about the people and, in some cases, images. One thing I will not be having them look for, though, is a picture of Queen Victoria’s husband, Albert – or Prince Albert. Our new firewall here is quite strict – no blogs, youtube, facebook, or anything like that. Fine with me. However, I did an image search for him and – despite having the safe search turned on in the google search engine, I stll saw drawings of Prince Alberts . . . which happen to be a ring through the penis! So I quickly took that item off the scavenger hunt. Disaster avoided. But so much for what gets blocked and what gets through!
