20 Dream WWE Matches That Only Happened ONCE!
10. CM Punk vs. Brock Lesnar
When: SummerSlam 2013
How did this happen once and once only?!
CM Punk bashed heads with legends like The Undertaker, John Cena and even The Rock on multiple occasions during his first 2005-2014 tenure in WWE. He'd only collide with Brock Lesnar once: SummerSlam 2013. Yours truly could've sworn there was a rematch on some 'B' level pay-per-view afterwards, but nah. There wasn't.
Lesnar got the win following a full 25 minutes of sheer drama, and it was back to the drawing board for Punk. He was real p*ssed off with WWE life by that stage anyway, so this was arguably his final top singles showing before leaving the promotion post-Royal Rumble 2014.
Brock currently being on ice means a rematch isn't likely today.
