Here's a specimen that's always in circulation by fax and email, not to mention appearing on several dozen Websites at any given time. It falls into the "legendary but true" category (see below).
This is an actual essay written by a college applicant to NYU in response to this question:
3A. IN ORDER FOR THE ADMISSIONS STAFF OF OUR COLLEGE TO GET TO KNOW YOU, THE APPLICANT, BETTER, WE ASK THAT YOU ANSWER THE FOLLOWING QUESTION:
ARE THERE ANY SIGNIFICANT EXPERIENCES YOU HAVE HAD, OR ACCOMPLISHMENTS YOU HAVE REALIZED, THAT HAVE HELPED TO DEFINE YOU AS A PERSON?
I am a dynamic figure, often seen scaling walls and crushing ice. I have been known to remodel train stations on my lunch breaks, making them more efficient in the area of heat retention. I translate ethnic slurs for Cuban refugees, I write award-winning operas, I manage time efficiently.
Occasionally, I tread water for three days in a row. I woo women with my sensuous and godlike trombone playing, I can pilot bicycles up severe inclines with unflagging speed, and I cook Thirty-Minute Brownies in twenty minutes. I am an expert in stucco, a veteran in love, and an outlaw in Peru.
Using only a hoe and a large glass of water, I once single-handedly defended a small village in the Amazon Basin from a horde of ferocious army ants. I play bluegrass cello, I was scouted by the Mets, I am the subject of numerous documentaries. When I'm bored, I build large suspension bridges in my yard. I enjoy urban hang gliding. On Wednesdays, after school, I repair electrical appliances free of charge.
I am an abstract artist, a concrete analyst, and a ruthless bookie. Critics worldwide swoon over my original line of corduroy evening wear. I don't perspire. I am a private citizen, yet I receive fan mail. I have been caller number nine and have won the weekend passes. Last summer I toured New Jersey with a traveling centrifugal-force demonstration. I bat 400.
My deft floral arrangements have earned me fame in international botany circles. Children trust me. I can hurl tennis rackets at small moving objects with deadly accuracy. I once read Paradise Lost, Moby Dick, and David Copperfield in one day and still had time to refurbish an entire dining room that evening. I know the exact location of every food item in the supermarket. I have performed several covert operations with the CIA.
I sleep once a week; when I do sleep, I sleep in a chair. While on vacation in Canada, I successfully negotiated with a group of terrorists who had seized a small bakery. I balance, I weave, I dodge, I frolic, and my bills are all paid.
On weekends, to let off steam, I participate in full-contact origami. Years ago I discovered the meaning of life but forgot to write it down. I have made extraordinary four course meals using only a mouli and a toaster oven. I breed prize-winning clams. I have won bullfights in San Juan, cliff-diving competitions in Sri Lanka, and spelling bees at the Kremlin.
I have played Hamlet, I have performed open-heart surgery, and I have spoken with Elvis.
But I have not yet gone to college.
(The author was accepted and is now attending NYU.)
Guide's note: It's more or less true. This essay (or a version of it), written by a high school student named Hugh Gallagher, was originally published in 1990 in Literary Calvalcade, a magazine of contemporary student writing (and later reprinted in both Harper's and The Guardian). There's some dispute over whether or not it actually got him admitted to NYU, but he did, in fact, graduate from there in 1994 and is now an author (unsurprisingly).
Gallagher's first novel, Teeth, was published by Pocket Books in March, 1998.
