I 'hacked' the turnitin.com algorithm and the teacher said I plagiarized?

Found some faults in the turnitin algorithm, and decided to test them. First off, i submitted my paper 'clean' to Writecheck, which uses turnitin's database and algorithm. It ped at 2%. Then I added some formatting... Embedding text as an object, making text an image, etc... I submitted this to turnitin as my ignment, for the lulz. Now the prof says I plagiarized. What do I do?
