Harry was bored, so was Ron; they decided to eat their beds. They did, but it wasn't very fun, so they decided to eat each other. Harry went first, but unfortunately, he ate Ron entirely, making it impossible for Ron to eat him back. Harry was sad and bored, and a little bloated, having eaten his bed, and having eaten Ron, who had also eaten a bed. Using the basic theory of energy and mass displacement, we take into account the adage of the mass of the bed to Harry's own mass, then we add the mass of Ron PLUS the mass of another bed, adding that to Harry's mass, which gives us the following equation.

Harry + Bed = 18000sq + 24000sq = 42000sq

Ron + Bed = 17600sq + 24000sq = 41600sq

Harry + Bed + (Ron + bed) = 18000sq + 24000sq + (17600sq + 24000sq) = 42000sq + 41600sq = 83600sq

Harry/DM + SM/Bed2 - (Ron X SM/Harry) = 18000sq/DM + SM/24000 x 2 - (17600sq X SM/18000sq) = 18000sq/24000sq + 41600sq/48000sq - (17600sq X 41600sq/18000sq) = 7500sq + 8666sq(continuous) - 17600sq X 2311sq(continuous) = 16166sq(continuous) - 40673600 = -40657434sq

HARRY = (AM/ CM) = HARRY = (40657434sq/18000sq) = HARRY = 2268.7463sq(continuous)

HARRY = (Harry + 2268.7463sq(continuous) HARRY = 20068.7463sq(continuous) Thereby meaning Harry had eaten Ron and two beds.

Venturing out into the corridors, Harry saw a mouldy Banana, which he quickly consumed. Bending over chewing also displaced mass, as did the muscle spasms used to ingest the food, giving us the following formula.

Harry + Banana = 20068.7463sq(continuous) + 800sq = 20068.7463sq(continuous)

Harry - exercise = 20068.7463sq(continuous) - 180sq = 19988.7463sq(continuous)

Harry decided to go to Hermione's room, since she was always fun to be around. Harry walked briskly over a short distance, giving us the following equation.

Harry - yet more exercise = 19988.7463sq(continuous) - 2800sq = 17188.7463sq(continuous)

As he reached Hermione's room, he realised he had forgotten to lock his own, and ran back, giving us this equation.

Harry - (more damn exercise/current exhaustion for previous exercise) x 1.1 = 17188.7463sq(continuous) - (3500sq/2800sq) X 1.1 = 17188.7463sq(continuous) - 125sq X 1.1 = 17188.7463sq(continuous) - 137.5sq = 17051.2463sq(continuous)

Harry was this angry.

Harry = usual body temperature + forgetting to lock the door = Harry = 27 degrees + 0.8 degrees = Harry = 27.8 degrees.

Harry then walked slowly back to Hermione's room, since he was tired, giving us the following equation.

Harry - (more exercise/addition of current exercise) X 1.1 = 17051.2463sq(continuous) - (1700sq/3500sq + 2800sq) X 1.1 = 17051.2463sq(continuous) - (1700sq/6700sa) X 1.1 = 17051.2463sq(continuous) - (.2567(continuous)) X 1.1 = 17051.2463sq(continuous) - .28637sq(continuous) = 17050.9596

Harry - (previous exercise X recent additional exercise)/(Harry/100) = 17050.9596 - (2800sq X 1700sq)/(17050.9596/100) = 17050.9596 - 476000/1705.09596 = 17050.9596 - 27963.1837103871204750285606723640673096593 = 99087.6784726405723023(continuous)

When Harry walked inside Hermione and Ginny's room, he saw Hermione and Ginny had also eaten their beds, and that Hermione had eaten Ginny. Harry, being the quick thinker that he was, ate Hermione, and washed her down with a vase of bleach, giving us the following equation.

Harry = Dead.
