How Will Lesnar vs Punk Match End At #Summerslam?

There is still no definitive plan for the ending of Brock Lesnar vs.CM Punk at SummerSlam, which of course is a week away. The match was originally scheduled to main event the show, however, the talk now is that WWE Champion John Cena vs. Daniel Bryan will close the show.
Suggested finishes for Punk vs. Lesnar have included a double count out and outside interference. The bout really books WWE into a corner because it’s lose/lose for either Lesnar or Punk to go under. One observer notes that no finish can be ruled out, no matter how “stupid” or “far fetched.”
