Greatest Pay Per View Ever?

I know it's hard for a brand-exclusive Pay-Per-View to claim this title, because usually the joint ones (Royal Rumble, Summerslam, Survivor Series, and Wrestlemania) are the more memorable ones. However, 15 years after the 1991 WCW Great American Bash (which, ironically, I have on tape) was dubbed the "worst pay-per-view in wrestling history", the 2006 version made some milestone history. First of all, Bobby Lashley, the Great Khali, and Mark Henry all had to be scratched at the last second due to for real injuries. Henry with the torn ACL, and Lashley and Khali with, oddly enough, liver problems. Secondly, all Smackdown! champions were in action, with all but Cruiserweight Champion Gregory Helms being in a title match. The bash also featured the first ever Punjabi Prison match. Originally scheduled to be The Great Khali vs. The Undertaker, Khali, as mentioned before, was a late scratch due to liver problems, and GM Theodore Long appointed The Big Show as his opponent. In arguably the bloodiest match in WWE history, the Undertaker wound up victorious when he was the one who escaped from the large bamboo structure. Next, fans witnessed fan favorite Batista snapping on Mr. Kennedy. Finally, in one of the most controversial heel turns in the history of wrestling, Chavo Guerrero turned on Rey Mysterio hitting him with a steel chair and allowing Booker T to become the new World Heavyweight Champion. I can honestly say that people who follow the WWE closely will always remember that one for the simple fact that the legacy of Eddie Guerrero brought the two together. I sincerely hope that this feud is not being carried out in the name of the late Eddie Guerrero. There are just certain lines that you don't cross. However, this pay-per-view is that Smackdown! needed to get back on par with the excitement of RAW and it gave itself alot of momentum leading up to Summerslam on August 20.
