Season Two
It is known that he smokes cigarettes, as Brittany tells him that he is not off the hook just because he is getting interviewed. She knew that he had been smoking again, which leads to confusion as to how the cat is actually getting the money to buy them, and to how he is actually getting them.
Lord Tubbington was put up to be interviewed as a quick replacement for Brittany's best friend, Santana Lopez, who cancelled on Brittany for an unspecified reason.
