Mr. & Mrs. Barton (Or, Why Natasha Sends Jennifer Aniston an Annual Apologetic Fruit Basket) by kuhori_rei
Natasha/Clint; NC-17; AU/humor/romance/spy antics; 13763 words
Summary: Five years before they meet as Hawkeye and the Black Widow, they meet as Clint and Natasha. There is a romance, a marriage, and then, predictably, everything goes absolutely to hell, and Clint still thinks they should be getting royalty money from the DVD sales of Mr. & Mrs. Smith. (Or: boy meets girl. Boy and girl fall in love. Boy and girl get married. Boy and girl neglect to do background checks.)

This fic is totally delightful; charming and romantic (not to mention hot). The plot of Mr. and Mrs. Smith fits beautifully for these characters.
