In you are in any way a fan of the Avengers' Black Widow or Parker from Leverage, go check out some great AU fanfic from a talented writer, Liana Mir. She captures the characters from both franchises perfectly.
Especially, Elliot's irate phone call to Clint after Parker is invited to Natasha's baby shower. I can just hear Hardison breathing into a paper bag in the background.
*I read the latest installment yesterday, and I'm still giggling.*
