In my opinion the greatest sitcom moment ever was when Mike on Growing Pains said to his sister that he found a foolproof way of cheating... "They'll never catch me... I'm writing the answers... in my brain."
(It was all in the delivery.)

I just had to store a lot of stuff in my brain, but finals are done: Latin "finis" (finis - 3rd declesion parasyllabic adjective, masculine feminine "i" in ablative and "ium" genitive plural, for neuter form add "ia" in nominative and accusitive plural).
