You have to know my dog to really appreciate this but here's a modified version of what I wrote:
Dear (Admissions Committeee Chair's name)
My name is Louie and I don't have and AMCAS ID number. I am writing about my mommy, threeeyedfrog even though she didn't list me as a dependent on her AMCAS application.
I have known Ms. threeeyedfrog quite intimately for the past 4 months and I can honestly say that she should go to your medical school. Even though she sometimes upsets me by cleaning my eye gooies, I know she would be a good doctor. For example, we have been studying for the MCAT together for the past several weeks. I help keep her motivated by opening her notebooks with my nose when she closes them.
Also, Ms. threeeyedfrog has already done several good things. She has fed, clothed, and babooshkad (yiddish word for babied) me all summer. I especially think she should get in because I went to her interview with her and I gave your medical school complimentary gardening from my natural water supply. (He was in the car when my mom dropped me off and he peed on the campus! I was mortified at the time). Not only did this save you money, but it made your medical school stand out from your competitors, who did not benefit from my generosity. I promise to continue my gardening efforts if only you people would accept my mommy to your school.
Lastly, I don't mean to sound threatening, but I'm a mean little man at heart and if she does not get in, I will come over there and yell my head off at all of you. I'm not bluffing. I have a lot of pent up anger and a mouth who's smell can only be likened to that of sewage. Therefore, you are left with two options. You can either accepted my mommy, Ms. Threeeyedfrog and receive complimentary gardening from an expert in the field or you can reject my mommy and bear the wrath of my anger. Here's a preview of option 2: RAHRAHRAHKKKKKKKKKKKKKRRRRRRRRRRRRRRRRA!
You're all smart doctors and I'm sure you'll choose wisely. For your assistance, I have enclosed some complimentary fertilizer in this note.
Most sincerely and respectfully,
Louie, the dog
