Dear Yale,
Aaron is one of the most top-notch students that I have met in my entire life, and trust me, I meet a lot of high quality students. There is no other student that I would recommend more to have matriculate at your campus. And, since the letter thing seemed to work with Stanford, you must take my advice. You would be doing yourself, your faculty, and your students a disservice if you were to reject this fine young scholar. Also, it wouldn't hurt to give him a free ride, too.
Sincerely,
Gordon.
Seriously, though, don't worry, you will get in. If a crazed lunatic such as I can get accepted, then you'll be a shoo-in. If not, you can give me a million punches in the face. I guarantee it.
