 * My final contribution, DA WORLD'S FIRST ANIMATED EXPLOIT!, is the foundation
 * for the next generation of OpenBSD exploits, crafted to burn Theo's eyes and make
 * him spend countless hours not only exercising his supreme reversing skills
 * but also delay his already deadly slow patch release timing. Hopefully every
 * fucktard out there willing to release an exploit for one of the many OpenBSD
 * locally exploitable issues, will give this insanely advanced code a good use.
 * Make sure you include some sanity checks (ie. if uid == 0 and hostname ==
 * cvs.openbsd.org make it do something creative like updating their index.html
 * once in a while).
 *
 * I would like to thank the following people for all the support, fun and
 * inspiration during my pilgrimage through the incredibly broken community known
 * as the security industry:
 *      Jesus H. Christ, Brute Dong, Bob, GOBBLES, towlie, noir and spender.
 *
 * I could name several people that I would love to either curbstomp or rape
 * anally (enjoying every inch of their rectum, though many of them would enjoy
 * the experience too, i know you dig dicks guys!), but I'll be a nice kid and
 * simply say that I love how this hdm, jf, FAilja, et al are nothing but
 * cock monglers. I enjoy how some of them have lost their jobs or got banned
 * by US immigration. And I also thank McDonalds for making you fatfucks get more
 * obese and ugly every year. And I'm sorry for the poor strippers that have to
 * stand the reality of being the only thing ressembling a woman you've ever had
 * the opportunity to see naked, besides your crack head cock-gobbling mom when
 * she sodomized you with a chop stick (and we know you liked it).
 * Hehehehe. BANANA! BANANA! BANANA! BTW, has gadi evron stopped crying for cocks
 * on craigslist men seeking men board? That fat fuck is sick. LULZ!
 *
 * OpenBSD is obsolete, aged, poorly designed, worsly developed and horribly
 * maintained. And led by a guy who needs to take his head out of his frozen
 * Canadian ass. FUCK YOU THEO, I'VE GOT YOUR DARPA FUNDING!
 *
 * This exploit abuses an old bug to gain root privileges on an OpenBSD 4.0
 * system. The ipv6 bug was never fully implemented because this shit made
 * me get a brain tumor. FUCK YOU THEO! LULZ LULZ LULZ LULZ LULZ LULZ LULZ
