Olaf the Stout is an inspirational viking warrior. He was a short little fella with a huge gut. He wielded an axe twice his size.

In a strange fit of drunken berserking rage, he tied a rope around the London Bridge, tied the other end to his boat, and pulled the entire thing over! And thus, the nursery rhyme was born.

Later in life, Olaf converted to Catholicism. He was ordained a saint after he died. In the belief of many catholics, one must perform three miracles/plagues in order to become a Saint. In Olafs case, he resurrected two people and started a disease that killed several thousands of people.

Even after that vikings death, he killed people. Thats awesome. I salute you, Olaf the Stout.
