1. What is the answer?

Hundreds of Ravenclaws stood by the door, begging and pleading to be let in. It was three in the morning, and no one had figured out the riddle. "The answer to what?" they cried, voices shrill and tired. The House was almost reduced to tears, when Luna Lovegood, a first year, waltzed to the front of the line, head buried in a book.

She banged into the door, only looking up when it bellowed, "What is the answer?" She glanced up, muttered, "42," and walked through the now open door. With a small smile, she slipped A Hitchhiker's Guide To The Galaxy in her bag.

2. What makes you think she's a witch?

Once again, no one could figure out the riddle. And, of course, the Ravenclaws forgot about Luna, as she had already established herself as a lunatic. Various cries rang out, not the least being, "She can do magic!" But the door wouldn't budge. The seventh years were sobbing, knowing time was ticking away from studying, as their Potions notes were in their dorms.

Finally, around midnight, Luna came wandering up to the door. After listening to the question, she nodded. "She weighs the same as a duck, therefore being made of wood, she is obviously a witch." With a casual wave of her hand, she continued on inside.

3. When can you own the earth?

When the door posed this question, everyone knew what to do. "Find Loony!" Ravenclaws scattered in all directions, after having a Knut charmed to alert them if someone else found her first. They tore around the castle, searching desperately for the girl they knew would know the answer.

Three hours later, a triumphant sixth year led Luna back to the entrance to the Common Room. The Ravenclaws cheered, and parted to let her step up to the door. After listening to the question, she looked thoughtful for a moment. "How does it go?" She murmured to herself. "Aha! You must be able to paint with all the colors of the wind!" And the door swung open. Luna was lifted into the air, and carried in.
