You never should mess with uncle Sam.

I am very gifted in filling out forms, particularly American ones. One time, as I was filling out the CBP declaration before landing in Newark, I omitted the 'f' in my last name. I was tired and did a sloppy job. You can imagine what kind of procedure you're subjected to, if you don't "remember your own name".
This Friday, at the American consulate in Tel-Aviv, a similar story. I approached the 3rd station, and was politely greeted by the secretary. First question - What month were you born in? - April. - Are you sure? - Yes, I'm sure, I was born on April 15th. - Then why did you fill out March? - What??! - You wrote here that you were born in March. - I am sorry, I made a honest mistake. - Okay, let me correct that for you.
Damn those computerized forms. One scroll of the mouse, and the month changes. The rest of the interview was pretty standard. I'll get the visas this week.
