I went to my first one a while ago... a bunch of the chiefs had me play a practical joke on another one of the chiefs. They all laughed their asses off and said "nice work what's your name ok go home."

I haven't gotten an email for another one since then. I'm past a year now. Oh yeah and I figured I'd go in for a second one a couple months ago and the chief pilot couldn't pull up the database, so he said not to worry about it and sent me home.

In short, don't worry about it.
