Maybe it's just me, but I don't really see the point in writing a letter like this - there was nothing in the acceptance they sent you that would warrant a snide response, and it makes it look like it would have been a better choice for them to accept someone else in your place. Being a qualified candidate does not qualify you to be rude.
On top of that, it's really not wise to burn any bridges you don't have to, especially over something as trivial as a grad. school acceptance (and when you were accepted, no less!). Hopefully your letter will not be noted anywhere, and you will never have to do any work in the future with anyone that may see and remember it.
I'm sure plenty of people will get a kick out of this, though, I just don't really happen to be one.
What baby duck monge said.
What a jerk. You're not the only one in the whole world who got accepted.
