One of the best ITP I have seen so far was submitted by my friend Josselin Mouette to debian-devel yesterday :

Package: wnpp
Severity: wishlist
Owner: Josselin Mouette <joss@debian.org>
* Package name : 09F911029D74E35BD84156C5635688C0
Version : 09F911029D74E35BD84156C5635688C0
Upstream Author : MPAA <antipiracy@mpaa.org>

Programming Lang: Hex
Description : l33t h4x0r numb3r

This package contains the "09F911029D74E35BD84156C5635688C0" number. It
is a very cool number, which, among other things, can be used by a wide
range of HD-DVD deciphering applications.

A small library is provided to access this number in applications. The
get_09F911029D74E35BD84156C5635688C0 C function returns a pointer to a
16-byte structure containing this number.

Altough he does not say how this package will deal with endianness problems, I am sure this is a must-have package.

In the same line, I also liked Samuel Hocevar's post and Neil McGovern where the number is color encoded in a picture. However, it looks like the DMCA law is the problem, not the copyright on the number per se.
