Fanfiction recs for Genius Kurt

[mslydia.livejournal.com]

Title basically says it all, I am looking for Genius/Extremely Smart!Kurt, I don't have a preference to where it is posted. Kurt centric is preferable for this, but any pairs are fine for me as well, I am not picky.
Thanks a bunch in advance :)

Looking for a Story (Puckleberry as Kids)

[crazyjansurfer.livejournal.com]

I'm looking for a one shot (Puckleberry). Puck and Rachel are little kids and they are going trick or treat. Rachel is dressed a the pink power ranger and I think Puck is the white one. Rachel is complaining because she wanted to be a princess. Puck says no because last year they dressed up the way she wanted, and it's his turn. They go out with Tina, Mike and Kurt. They also meet up with other gleeks. Puck gets mad when he finds out that next year Rachel wants to be Tinker Bell to Kurt's Peter Pan. He leaves them. The rest of the story is Rachel trying to find Puck again. They reunite at the end.
