Not one to be denied a party, the sage four year old sat down on his bed, and tried to think of a way to go to downstairs and mingle, without being caught, and sent back to bed. He could tie a red blanket around his neck, and wear his Superman pajamas and go downstairs, but Superman was a do-gooder boy scout, who, when asked to go upstairs and go to bed, would be forced to comply. He had once gone downstairs naked, imagining himself invisible, and that had made his parents very cross. What, then? He dug through his closet, and there he found The Answer To His Problems. A Darth Vader mask. Who would dare send Darth Vader off to bed at nine PM? Maybe Emperor Palpatine, but that's about it (these being the days before anyone knew of whiny emo Anakin).
This is how there came to be The Greatest Party Ever, in which a bunch of suited up water cooler types, sat around the couches, and leaned in doorways, listening to a tiny Lord Vader regale them with stories about dinosaurs, and computer games, and other things that strikes Tiny Vader's fancy. Tiny Vader is, at no point, sent upstairs by the little boy's parents, but eventually falls asleep on the chair, and wakes up the next morning clutching the Vader mask like a teddy bear.
This has nothing to do with the story I'm about to tell you, except that when Jim said, "So I've been telling a story about you recently that involves Darth Vader, and I thought you should know." This was the only story I could think of.
context is much less work-safe, quoted with permission, and busy interrogating princesses.
