The main event for this pay per view was a 60 min iron man match (most falls in an hour wins) for the WWF title. The participents were HHH (the CHALLENGER) v The Rock (the Champion) with Shawn Michaels (HBK) as the guest referee. The first slip up was in the intros, as HHH, the challenger was introduced as the champion!! The biggest slip up was the end of the match though. The scripted ending was that HHH's cohorts would come to the ring and assault the Rock with the fall count 5 each. The Undertaker (making his return after a 9 month absence) would come down and clear the ring of them and Chokeslam and Tombstone HHH. This would mean that The Rock was dqd by HBK and HHH would lead 6-5. The Rock would then cover HHH but with HBK about to make the 3 count the 60mins would expire meaning HHH would win.
However they sent the Undertaker out to late and the 60mins expired as he was chokeslaming HHH and leaving the planned ending null and void. Luckily HBK was looking at The Undertaker when he nailed the move and some quick thinking by HBK (telling the announcer to dq The Rock due to outside interference) everything was ok. This also explains why the 'did HBK screw the Rock angle ' which aired next night on raw was dropped and never ended, as it was never meant to be but had to be introduced to cover up the ending flub.
