Sergeant Sam Roderick

Sergeant Sam Roderick ( aka Mr Sharky) is the antagonist from the animated TV series Spongebob Squarepants episode, "Mrs. Puff, You're Fired". After Mrs. Puff was fired for failing to teach Spongebob how to drive so many times, she was replaced by Roderick. He was very strict, making Sponebob learn every inch of a difficult driving course, first by crawling and then by walking and finally by running through it whilst blindfolded. Soon Spongebob could complete the course while driving blindfolded. When it came to Spongebob's test for his license he attemped to put on his blindfold, but was told not to. But Spongebob never learned how to drive without his eyes closed and was soon out of control. Roderick tried to stop the boat, but was run over. Spongebob failed his test and Mrs. Puff was hired again. It was never shown what happened to Roderick afterwards.
