Disclaimer: I own neither HP nor Halloween. Duh.
Lord Voldieshorts was so bored that he might have died because of boredom if he wasn't already immortal. He'd tortured several muggles of course, but just not enough to make him feel good. So he summoned Wormtail, to Crucio him for a while. Poor Wormtail stumbled inside and kneeled before him.
But just as Voldie was raising his wand, Wormtail stuttered: "P-p-please, my L-l-l-ord. D-do not torture me today. I-I should go home early and make my halloween costume."
He tortured him anyway, than asked: "I order you to tell me what is Halloween right now!"
"Y-you don't know what H-halloween is??" Wormtail asked, astonished.
"Of course I do." Voldie lied, punishing Wormtail again for daring to suggest that he didn't know something. "But I want to hear it from you."
"I-it's something we celebrate on every October 31st, my lord. We wear costumes, and go from door to door, asking for sweets! Also, there are Halloween parties all over the place that night, and everywhere is decorated ever so spookily." Wormtail suddenly stopped speaking, his eyes shining with joy. After being tortured again for stopping for an entire second, he begun speaking again in a very excited voice: "M-my Lord, w-why don't we have a Halloween party, too? It would be so f-"
"Crucio!" Voldie shrieked, angry that Wormtail had thought of something he hadn't. "It's an awful idea!" He screamed spitefully. Wormtail started to cry. Voldie remained indifferent, thinking hard. Finally, he said: "Wormtail, I have an idea. I'm going to host a Halloween party for my precious Death Eaters." Wormtail stopped crying, and started clapping like an infant, having forgotten that it was actually his idea, not Voldiekins's.
"It's such a wonderful idea my Lord! I-I wil tell everyone to start making their costumes and preparing the decorations. Ooh, we must also buy lots and lots of sweets! Oh my Lord, it's gonna be SO much fun!" He giggled delightedly.
"Yeah, yeah, you do all that." Voldemort said dismissively. Than, for no particular reason at all, he Crucio'd Wormtail again, than finally let him skip off home in joy to prepare his costume.
When Wormtail was gone, he stretched, yawning. He was suddenly SO tired, he needed to do something fun to relax. Contrary to what everyone believes, torturing muggles, mudbloods, half bloods, blood traitors and death eaters wasn't Lord Voldemort's favorite free time activity (although it probably came 2nd). No, he didn't do any of these. Instead he reached for the CD player, and pressed play. As the joyful tune of Girlfriend by Avril Lavigne filled the dark, scary room; the great Dark Lord sung "Hey hey, you you, I want to be your girlfriend!" as loudly as he could and danced wildly, while plotting his marvelleous Halloween party, of course.
