While renewing my drivers license earlier this afternoon:
DMV employee: "How much do you weigh?"
Me: "Oh, man! You need to know that, too? I just gave birth 27 days ago."
DMV employee: "Well, how much would you like to weigh?"
Me: "OMG, really?!"
(Note: we settled on my prepregnancy weight. Not 115 pounds, like Trevor suggested.)
