Kirk makes a list (possibly similar to Skippy's List?), deaged crew
If I remember correctly, I think it was an old kink meme fic from around when ST XI first came out. The whole crew's deaged to just around pre-adolescence (~ten years, I think?) and Kirk writing a list of things into his captain's log (I think of things he can't do? Or a list of why he's awesome, something of that sort.) It's pretty cracky with some thrown-in Kirk/McCoy and Sulu/Chekov.
I remember there was this whole part about how Sulu had stacked books about corn and fencing underneath his chair so he could reach the helm, and Kirk asked to read one of the books sometime (the corn one) and Sulu mistakenly thinks he means the fencing one.
I recently lost all my ST bookmarks, and I really just want to figure out what the name is. Thanks!
