A large group of about 20 or 30 wizards was gathered on the Moon. The Transcendent Pig walked into the center of the group. Every wizard stopped what they were doing and shouted the same question at the Pig-"What's the meaning of life?"
On the edge of the group, a teenage girl with a yellow '1' on her shirt spoke up. "Must a name mean something?" she quoted. All attention was on her as the wizards turned from the Pig to the girl. "Does life have to have a meaning?" she continued. "If it does, it's not because the Powers That Be or the One gave it one. If life has a meaning, it's because you give it one. So don't ask a pig the meaning of life. Ask yourselves."
The girl vanished without misplacing any air; when the wizards looked, the Transcendent Pig had done the same.
A/N: I think that it is hilarious that wizards ask a pig the meaning of life. Even if he is transcendent, he's a pig.
