The Circle of Crime are a villainous group in Marvel comic books who have encountered the Hulk on a few occasions. Their members are Ringmaster, the Clown, Bruto, the Strongman, the Human Cannonball, the Great Gambonnos, Princess Python and Live Wire. On one occasion, the Circus of Crime were attempting to rob a casino, but Bruce Banner happened to be there at the same time. Amidst all the furore, Banner transformed in to the Hulk and went after each member of the group. He took out the majority of the members of the Circus of Crime but, just when he was about to get to the Clown, Python Princess's snake wrapped itself around the Hulk's head and neck and cut off his oxygen supply, in spite of his struggles, for long enough to knock him unconscious. That's right, the supposedly infinitely strong Hulk was choked out by a snake.
