WW Fic: Ask a Scientist (it's quantum physics)

Title: Ask a Scientist (it's quantum physics)
Fandom: West Wing
Pairing: Josh/Donna. Sam/Josh overtones.
Rating: G
Summary: There are some things Donna knows; there are others that she doesn't want to admit.
Spoilers: Set vaguely post-S4. Since S5 is a haze of Toby-annoyance and I've only seen halfway through that season, I can't vouch that it agrees with current canon.
Disclaimer: Originally Sorkin's. Certainly not mine.
Notes: Finished as part of the wip_it_good challenge (I just forgot to get it beta'd). Thanks to oxoniensis and celli for support. Thanks to Ben Lee for the title. Huge thanks to meadowlion for tracking down my stray tenses, correcting my comma-usage, and making this story far more readable.

I'm posting this because I'm powerless to resist celli. From AIM:

Celli: It's like Choose Your Own Kinky Porn

Me: Hee!

Me: I need a book like that.

Me: It'd be all:
"Rodney groaned and John..."
If John pushed him down to the bed and undid Rodney's belt, go to page 63.
If John moaned as Rodney dropped to his knees in front of him, go to page 17.

Celli: ahahahahah!

Celli: you need to post that.

Celli: everyone will die laughing.
